What is the authenticity of the saying: "O Allah, for You I fasted..." when the fasting person breaks his fast?
Machine translationRead the Arabic original
May Allah reward you. Some people say at the adhan: "O Allah, for You I fasted." Is there anything in that?
There is a weak hadith regarding this. If he says it, there is no blame on him, but it is not authentic; the hadith is weak. However, its meaning is correct: he fasted for Allah and broke his fast for Allah. But the hadith is not called a sunnah. It is said that the type of supplication is a sunnah. The type of supplication—that you broke your fast—is a sunnah, and it is hoped that it will be accepted.
Q: I mean—may Allah reward you—before the adhan of Fajr?
A: At the time of breaking the fast and at the time of fasting, it is all the same. If he says it, there is nothing wrong with it, but it is not a sunnah.
