وَعَنِ اِبْنِ عُمَرَ رَضِيَ اَللَّهُ عَنْهُمَا
«أَنَّ اَلْعَبَّاسَ بْنَ عَبْدِ اَلْمُطَّلِبِ رضى الله عنه اِسْتَأْذَنَ رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: أَنْ يَبِيتَ بِمَكَّةَ لَيَالِيَ مِنًى، مِنْ أَجْلِ سِقَايَتِهِ، فَأَذِنَ لَهُ»
‘Al-Abbas ibn Abdul Muttalib asked permission from the Prophet (sallallahu alayhi wa sallam) to stay at Makkah during the nights of Mina in order to provide drinking water (from Zamzam) to the pilgrims, and the Prophet (sallallahu alayhi wa sallam) allowed him.’ Agreed Upon.
