The Ruling on Saying "What Allah Wills and You Will"
Machine translationRead the Arabic original
The questioner:
If he says, "If you will."
The Shaykh:
Then, nothing is said except something. Not "if you will," but rather, "If Allah gives, He gives such and such, may Allah reward you with good. If He wills, He gives such and such, provided it does not contradict [His will]." As for saying, "If not for Allah, or what Allah willed," one does not say, "and what so-and-so willed." May Allah make it good. "If not for so-and-so, the knowledge of the Hijaz would have been lost." No, the correct way is to say, "If not for Allah, then so-and-so." This is the correct way. Yes.
