What is the ruling on one who drinks after the Fajr adhan?
Machine translationRead the Arabic original
The questioner : A man. Yes. A man drank water and milk after the adhan, and when he went to the mosque, one of the worshippers was in the first rak'ah or was descending from the prayer. Peace be upon you. May Allah keep you safe.
The Shaykh : We say that this man who drank milk and water after the Fajr adhan, if he did not hear the adhan, or if he heard the adhan and thought it was the first adhan, then he has not committed a sin and he owes nothing for that day; rather, his fast is complete and valid. We will mention the evidence for this, if Allah wills, in the next lesson, as we promised.
