Sayyiduna Abdullah bin Umar (may Allah be pleased with them) narrates: Sayyiduna Abbas bin Abdul Muttalib (may Allah be pleased with him) sought permission from the Prophet (peace and blessings of Allah be upon him) to spend the nights of Mina in Makkah, because he had to provide (Zamzam water) to the pilgrims. So the Prophet (peace and blessings of Allah be upon him) granted him permission due to his service of providing water.
