PROPHET MUHAMMAD (ﷺ) said:
Whoever killed a person having a treaty with the Muslims, shall not smell the smell of Paradise though its smell is perceived from a distance of forty years.

Narrated: Abu Hurairah
"It was said: 'O Messenger of Allah (ﷺ), pray against the idolaters.' He (ﷺ) said: 'I was not sent as an invoker of curses, rather I was sent as a mercy."

Narrated: Abu Ad-Darda
PROPHET MUHAMMAD (ﷺ) said:
"Shall I not inform you of what is more virtuous than the rank of fasting, Salat, and charity?" They said: "But of course!" He said: "Making peace between each other. For indeed spoiling relations with each other is the destruction."

PROPHET MUHAMMAD (ﷺ) said:
The strong is not the one who overcomes the people by his strength, but the strong is the one who controls himself while in anger.

PROPHET MUHAMMAD (ﷺ) said:
A faithful believer remains at liberty regarding his religion unless he kills somebody unlawfully.

PROPHET MUHAMMAD (ﷺ) said:
One of the evil deeds with bad consequence from which there is no escape for the one who is involved in it is to kill someone unlawfully.

PROPHET MUHAMMAD (ﷺ) said:
The first cases to be decided among the people (on the Day of Resurrection) will be those of blood-shed.

PROPHET MUHAMMAD (ﷺ) said:
Religion is very easy and whoever overburdens himself in his religion will not be able to continue in that way. So you should not be extremists, but try to be near to perfection and receive the good tidings that you will be rewarded; and gain strength by worshipping in the mornings, the afternoons, and during the last hours of the nights.

PROPHET MUHAMMAD (ﷺ) said:
May the extremists perish,
May the extremists perish,
May the extremists perish.

PROPHET MUHAMMAD (ﷺ) said:
Whoever believes in Allah and the Last Day Should talk what is good or keep quiet.

Narrated: Mu'awiyah bin Jahimah As-Sulami
Jahimah came to the Prophet Muhammad (ﷺ) and said:
"O Messenger of Allah! I want to go out and fight (in Jihad) and I have come to ask your advice." He said: "Do you have a mother?" He said: "Yes." He said: "Then stay with her, for Paradise is beneath her feet."

PROPHET MUHAMMAD (ﷺ) said:
The best of you is the best to his wives, and I am the best of you to my wives.

PROPHET MUHAMMAD (ﷺ) said:
A believing man should not hate a believing woman (wife); If he dislikes one of her characteristics, he will be pleased with another.

PROPHET MUHAMMAD (ﷺ) said:
Kindness is not to be found in anything but that it adds to its beauty and it is not withdrawn from anything but it makes it defective.

PROPHET MUHAMMAD (ﷺ) said:
The best amongst you are those Who have the best manners and character.

PROPHET MUHAMMAD (ﷺ) said:
You gain no victory or livelihood except through (the blessings and invocations of) the poor amongst you.

PROPHET MUHAMMAD (ﷺ) said:
Seek your weak for me. For indeed you sustenance and aid is only by your weak.
