Narrated Ibn `Umar: Al `Abbas bin `Abdul-Muttalib asked the permission of Allah's Apostle to let him stay in Mecca during the nights of Mina in order to provide the pilgrims with water to drink, so the Prophet permitted him.

Narrated Ibn `Abbas: Allah's Apostle came to the drinking place and asked for water. Al-Abbas said, "O Fadl! Go to your mother and bring water from her for Allah's Apostle ." Allah's Apostle said, "Give me water to drink." Al-Abbas said, "O Allah's Apostle! The people put their hands in it." Allah's Apostle again said, 'Give me water to drink. So, he drank from that water and then went to the Zamzam (well) and there the people were offering water to the others and working at it (drawing water from the well). The Prophet then said to them, "Carry on! You are doing a good deed." Then he said, "Were I not afraid that other people would compete with you (in drawing water from Zamzam), I would certainly take the rope and put it over this (i.e. his shoulder) (to draw water)." On saying that the Prophet pointed to his shoulder.
