PROPHET MUHAMMAD (ﷺ) said:
If you were to rely upon Allah with the required reliance, then He would provide for you just as a bird is provided for, it goes out in the morning empty, and returns full.
Anas bin Malik narrated that a man said:
"O Messenger of Allah (ﷺ)! Shall I tie it and rely (upon Allah), or leave it loose and rely (upon Allah)?" He (ﷺ) said: "Tie it and rely (upon Allah)."
PROPHET MUHAMMAD (ﷺ) said:
At-Tiyarah (Bad omen) is Shirk, At-Tiyarah is Shirk, At-Tiyarah is Shirk. All or us have some of that, but Allah removes it by means of reliance upon Him.
Ibn 'Abbas narrated:
"I was behind the Prophet (ﷺ) one day when he (ﷺ) said:
'O boy! I will teach you a statement:
Be mindful of Allah and He will protect you. Be mindful of Allah and you will find Him before you. When you ask, ask Allah, and when you seek aid, seek Allah's aid. Know that if the entire creation were to gather together to do something to benefit you- you would never get any benefit except that Allah had written for you. And if they were to gather to do something to harm you- you would never be harmed except that Allah had written for you. The pens are lifted and the pages are dried.'"
PROPHET MUHAMMAD (ﷺ) said:
A slave (of Allah) shall not believe until he believes in Al-Qadar (Destiny), its good and its bad, such that he knows that what struck him would not have missed him, and that what missed him would not have struck him.
PROPHET MUHAMMAD (ﷺ) said:
1) The strong believer is better and more beloved to Allah than the weak believer, although both are good.
2) Strive to do that which will benefit you and seek the help of Allah, and do not feel helpless.
3) If anything befalls you, do not say: "If only I had done (such and such), then such and such would have happened," rather say: "QADDAR ALLAHU MASHAA'A FA'AL (Allah has decreed and what He wills He does)."
4) For; "if only" opens the door to the work of the Shaitan.
Anas bin Malik narrated:
"There were two brothers during the time of the Messenger of Allah (ﷺ). One of them used to come to the prophet (ﷺ, and the other had some business. The businessman among them complained to the Prophet (ﷺ) about his brother, so he (ﷺ) said:'Perhaps you are provided for because of him.'"
