Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated Jabala bin Suhaim (Radi-Allahu ‘anhu):
At the time of Ibn Az-Zubair, we were struck with famine, and he provided us with dates for our food. ‘Abdullah bin ‘Umar used to pass by us while we were eating, and say, “Do not eat two dates together at a time, for the Prophet (Sallallahu ‘Alaihi Wa Sallam) forbade the taking of two dates together at a time (in a gathering).” Ibn ‘Umar used to add, “Unless one takes the permission of one’s companions.”
