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.  

أَنَّ الْعَبَّاسَ بْنَ عَبْدِ الْمُطَّلِبِ اسْتَأْذَنَ رَسُولَ اللَّهِ ﷺ أَنْ يَبِيتَ بِمَكَّةَ لَيَالِيَ مِنًى مِنْ أَجْلِ سِقَايَتِهِ فَأَذِنَ لَهُ  

A hadith like this has been narrated by 'Ubaidullah b. Umar with the the same chain of transmitters.  

عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ بِهَذَا الإِسْنَادِ مِثْلَهُ  

While I was sitting along with Ibn 'Abbas (Allah be pleased with him) near the Ka'ba, there came a bedouin to him and said: What is the matter that I see that the progeny of your uncle supply honey and milk (as drink to the travellers), whereas you supply al-nabidh (water sweetened with dates)? Is it due to your poverty or due to your close-fistedness? Thereupon Ibn 'Abbas said: Allah be praised, it is neither due to poverty nor due to close-fistedness (but due to the fact) that Allah's Apostle ﷺ came here riding his she-came, and there was sitting behind him Usama. He asked for water, and we gave him a cup full of nabidh and he drank it, and gave the remaining (part) to Usama; and he (the Holy Prophet) said: You have done Food, You have done well. So continue doing like it So we do not like to change what Messenger of Allah ﷺ had commanded us to do.  

مَا لِي أَرَى بَنِي عَمِّكُمْ يَسْقُونَ الْعَسَلَ وَاللَّبَنَ وَأَنْتُمْ تَسْقُونَ النَّبِيذَ أَمِنْ حَاجَةٍ بِكُمْ أَمْ مِنْ بُخْلٍ فَقَالَ ابْنُ عَبَّاسٍ الْحَمْدُ لِلَّهِ مَا بِنَا مِنْ حَاجَةٍ وَلاَ بُخْلٍ قَدِمَ النَّبِيُّ ﷺ عَلَى رَاحِلَتِهِ وَخَلْفَهُ أُسَامَةُ فَاسْتَسْقَى فَأَتَيْنَاهُ بِإِنَاءٍ مِنْ نَبِيذٍ فَشَرِبَ وَسَقَى فَضْلَهُ أُسَامَةَ وَقَالَ أَحْسَنْتُمْ وَأَجْمَلْتُمْ كَذَا فَاصْنَعُوا فَلاَ نُرِيدُ تَغْيِيرَ مَا أَمَرَ بِهِ رَسُولُ اللَّهِ ﷺ
