39:36Az-Zumar

'Allah is Sufficient for us and He Is the Best Disposer of affairs," was said by Abraham when he was thrown into the fire; and it was said by Muhammad when they (i.e. hypocrites) said, "A great army is gathering against you, therefore, fear them," but it only increased their faith and they said: "Allah is Sufficient for us, and He is the Best Disposer (of affairs, for us)." (3.173)

"The Messenger of Allah (s.a.w) said: 'How can I be comfortable when the one with the horn is holding it to his lip, his ears listening for when he will be ordered to blow, so he can blow.' It was as if that was very hard upon the Companions of the Prophet (s.a.w), so he said to them: 'Say: "Allah is sufficent for us and what a good protector He is, and upon Allah we rely." This Hadith is Hasan. This Hadith has been reported through other routes from 'Atiyyah, from Abu Sa'eed from the Prophet SAW, similarly.

Help me against them by afflicting them with seven years of famine similar to the seven years (of famine) of Joseph. So they were afflicted with a year of drought that destroyed everything, and they ate bones and hides. (One of them said), "And they ate hides and dead animals, and (it seemed to them that) something like smoke was coming out of the earth. So Abu Sufyan came to the Prophet (ﷺ) and said, "O Muhammad! Your people are on the verge of destruction! Please invoke Allah to relieve them." So the Prophet (ﷺ) invoked Allah for them (and the famine disappeared). He said to them. "You will revert (to heathenism) after that." `Abdullah then recited: 'Then watch you for the Day that the sky will bring forth a kind of smoke plainly visible.......but truly you will revert (to disbelief).' He added, "Will the punishment be removed from them in the Hereafter? The smoke and the grasp and the Al-Lizam have all passed." One of the sub-narrater said, "The splitting of the moon." And another said, "The defeat of the Romans (has passed).
