Ibn Umar (Allah be pleased with them) reported that al-'A'bbas b. Abd al-Muttalib (Allah be pleased with him) sought permission from Allah's Messenger (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.
A hadith like this has been narrated by 'Ubaidullah b. Umar with the the same chain of transmitters.
Bakr b. 'Abdullah al-Muzani said
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 Allah's Messenger (ﷺ) had commanded us to do.
