It was narrated from Umm Salamah that when the Prophet (ﷺ) performed the Subh (morning prayer), while he said the Salam, he would say:

TRANSLATION:
O Allah, I ask You for beneficial knowledge, goodly provision and acceptable deeds.

PROPHET MUHAMMAD (ﷺ) said:
When one of you reached the morning, then let him say:

TRANSLATION:
O Allah, by You we enter the morning, and by You we enter the evening, and be You we live, and by You we died, and to You is the Return.
(SUNAN TIRMIDHI Vol #6, Hadith #3391) (SUNAN IBN MAJAH Vol #5, Hadith #3868) (SUNAN ABU DAWUD Vol #5, Hadith #5068)

PROPHET MUHAMMAD (ﷺ) said:

Abdullah bin Masud said:
When morning came the Messenger of allah (ﷺ) would say:

TRANSLATION:
We have reached the morning and the dominion belongs to Allah and praise be to Allah, none has the right to be worshipped but Allah alone with no partner or associate. His is the dominion, to Him is praise and has power over all things. O Allah, I ask You for the good of this day and the good of what follows it and, I seek refuge in You from the evil of this day and the evil of what follows it. O Allah, I seek refuge in You from laziness and the evil of arrogance. O Allah, I seek refuge in You from torment in the Fire and torment in the Grave.

PROPHET MUHAMMAD (ﷺ) said:
Whoever says:

one hundred times will get the same reward
1) As given for manumitting (freeing) ten slaves;
2) And one hundred good deeds will be written in his accounts,
3) And one hundred sins will be deducted from his accounts,
4) And it (his saying) will be a shield for him from Satan on that day till night,
5) And nobody will be able to do a better deed except the one who does more than he.

NOTE : In Hadith of Sahih Muslim, it is freeing 100 slaves.

PROPHET MUHAMMAD (ﷺ) said:
Whoever says three times when he reaches the evening:

no poisonous sting shall harm him that night.

TRANSLATION:
I seek refuge in Allah’s Perfect Words from the evil of what he created.

PROPHET MUHAMMAD (ﷺ) said:
Whoever says:

ten times at the end of Al-Maghrib -
1) Allah shall send for him protectors to guard him from Shaitan until he reaches morning,
2) And Allah writes for him ten good deeds,
3) And He wipes from him ten of the destructive evil deeds,
4) And it shall be for him the equal of freeing ten believing slaves.

TRANSLATION:
One has the right to be worshipped but Allah, Alone, without partner, to Him belongs all that exists, and to Him belongs the praise, He gives life and causes death, and He is powerful over all things.

PROPHET MUHAMMAD (ﷺ) said:
When one of you reached the evening, then let him say:

TRANSLATION:
O Allah, by You we enter the evening, and by You we enter the morning, and by You we live, and by You we die, and to You is the Resurrection.

PROPHET MUHAMMAD (ﷺ) said:

When morning came the Messenger of allah (ﷺ) would say:

TRANSLATION:
We have reached the evening and the dominion belongs to Allah and praise be to Allah, none has the right to be worshipped but Allah alone with no partner or associate. His is the dominion, to Him is praise and has power over all things. O Allah, I ask You for the good of this night and the good of what follows it and, I seek refuge in You from the evil of this night and the evil of what follows it. O Allah, I seek refuge in You from laziness and the evil of arrogance. O Allah, I seek refuge in You from torment in the Fire and torment in the Grave.

PROPHET MUHAMMAD (ﷺ) said:
Whoever says in the morning and in the evening

a hundred times, none shall bring better than him on the Day of Judgment except one who did the same as him, or increased upon it.

TRANSLATION:
Glory is to Allah and with His Praise.

PROPHET MUHAMMAD (ﷺ) said:
If anyone says a hundred times in the morning:

And says likewise in the evening, no one from the creatures will bring anything like the one which he will bring.

TRANSLATION:
Glory be to Allah, the Sublime, and I begin with praise of him.

PROPHET MUHAMMAD (ﷺ) said:

QURAN 2:255
Allah - there is no deity except Him, the Ever-Living, the Sustainer of [all] existence. Neither drowsiness overtakes Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that can intercede with Him except by His permission? He knows what is [presently] before them and what will be after them, and they encompass not a thing of His knowledge except for what He wills. His Kursi extends over the heavens and the earth, and their preservation tires Him not. And He is the Most High, the Most Great.

PROPHET MUHAMMAD (ﷺ) said:
Say: “Say: He is Allah, the One (Surah Ikhlas)” and Al-Mu’awwidhatain (Surah Falaq & Surah Naas), when you reach evening, and when you reach morning, three times, they will suffice you against everything.

SURAH IKHLAAS
112:1 Say, "He is Allah , [who is] One,
112:2 Allah , the Eternal Refuge.
112:3 He neither begets nor is born,
112:4 Nor is there to Him any equivalent."

SURAH FALAQ
113:1 Say, "I seek refuge in the Lord of daybreak
113:2 From the evil of that which He created
113:3 And from the evil of darkness when it settles
113:4 And from the evil of the blowers in knots
113:5 And from the evil of an envier when he envies."

SURAH NAAS
114:1 Say, "I seek refuge in the Lord of mankind,
114:2 The Sovereign of mankind.
114:3 The God of mankind,
114:4 From the evil of the retreating whisperer -
114:5 Who whispers [evil] into the breasts of mankind -
114:6 From among the jinn and mankind."

PROPHET MUHAMMAD (ﷺ) said:
Whoever says in the morning:

1) He will have (a reward) equal to freeing a slave among the sons of Isma'il,
2) Ten bad deeds will be erased from (his record),
3) He will be raised (in status) ten degrees, and
4) He will have protection against Satan until evening comes.
When evening comes, (if he says likewise) he will have the same until morning comes.

TRANSLATION:
None has the right to be worshipped but Allah alone, with no partner or associate. His is the dominion and all praise is to Him, and He is Able to all things.

PROPHET MUHAMMAD (ﷺ) said:
If anyone says morning and evening;

Allah will be sufficient for him against anything which grieves him, whetherhe is true or false in (repeating) them.

TRANSLATION:
Allah is sufficient for me, there is none worthy of worship but He, in Him have I put my trust, and He is the Lord of the Mighty Throne.

PROPHET MUHAMMAD (ﷺ) said:
If anyone says three times:

He will not suffer sudden affliction till the morning, and if anyone says this in the morning, he will not suffer sudden affliction till the evening.

TRANSLATION:
In the name of Allah, when Whose name is mentioned nothing on Earth or in Heaven can cause harm, and He is the Hearer, the Knower.

PROPHET MUHAMMAD (ﷺ) said:

(SAHIH AL JAAMI Hadith #5820)

Narrated AbuBakrah:
AbdurRahman ibn AbuBakrah said that he told his father: O my father! I hear you supplicating every morning:

You repeat them three times in the morning and three times in the evening.
He said: I heard the Messenger of Allah (ﷺ) using these words as a supplication and I like to follow his practice.

TRANSLATION:
O Allah! I seek refuge in Thee from infidelity and poverty. O Allah! I seek refuge in Thee from punishment in the grave. There is no god but Thee.

Narrated AbuBakrah:
AbdurRahman ibn AbuBakrah said that he told his father: O my father! I hear you supplicating every morning:

You repeat them three times in the morning and three times in the evening.
He said: I heard the Messenger of Allah (ﷺ) using these words as a supplication and I like to follow his practice.

TRANSLATION:
O Allah! Grant me health in my body. O Allah! Grant me good hearing. O Allah! Grant me good eyesight. There is no god but Thou.

Narrated: Ibn Umar
Prophet Mohammed (ﷺ) never abandoned these supplications, every morning and evening:

TRANSLATION:
O Allah, I ask You for forgiveness and well-being in this world and in the Hereafter. O Allah, I ask You for forgiveness and well-being in my religious and my worldly affairs. O Allah, conceal my faults, calm my fears, and protect me from before me and behind me, from my right and my left, and from above me, and I seek refuge in You from being taken unaware from beneath me.

Abu Bakr said:
O Messenger of Allah (ﷺ), command me with something that I may say when I reach morning and evening.’ He (ﷺ) said: Say:

TRANSLATION:
O Allah Knower of the Unseen and the Seen, Originator of the heavens and the earth, Lord of everything and its Possessor, I bear witness that there is none worthy of worship except You, I seek refuge from You from the evil of my soul and from the evil of Shaitan and his Shirk.

PROPHET MUHAMMAD (ﷺ) said:
The most superior way of asking for forgiveness from Allah is:

If somebody recites it during the day with firm faith in it, and dies on the same day before the evening, he will be from the people of Paradise; and if somebody recites it at night with firm faith in it, and dies before the morning, he will be from the people of Paradise.

TRANSLATION:
O Allah, You are my Lord, there is no god but You. You have created me and I am Your slave and I am keeping my promise and covenant to You as much as I can. I seek refuge with You from the evil of what I do. I acknowledge Your blessing and I acknowledge my sin, so forgive me, for there is none who can forgive sin except You.
