Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated Anas (Radi-Allahu ‘anhu):
Zaid bin Thabit said, “We took the Suhur with the Prophet (Sallallahu ‘Alaihi Wa Sallam). Then he stood for the prayer.” I asked, “What was the interval between the Suhur and the Adhan?” He replied, “The interval was sufficient to recite fifty verses of the Quran.”
