Ibn Umar (Allah be pleased with them) reported that al-'A'bbas b. Abd al-Muttalib (Allah be pleased with him) sought permission from Messenger of Allah ﷺ to spend in Mecca the nights (which be was required to spend) at Mina on account of his office of supplier of water, and he (the Holy Prophet) granted him permission. (Using translation from Muslim 1315a)  

أَنَّ الْعَّبَاسَ بْنَ عَبْدِ الْمُطَّلِبِ اسْتَأْذَنَ رَسُولَ اللَّهِ ﷺ لِيَبِيتَ بِمَكَّةَ لَيَالِيَ مِنًى مِنْ أَجْلِ سِقَايَتِهِ «فَأَذِنَ لَهُ»

عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ نَحْوَهُ
