It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them) that Sayyiduna Abbas bin Abdul Muttalib (may Allah be pleased with him) sought permission from the Messenger of Allah (peace and blessings be upon him) to stay in Makkah during the nights of Mina because he was responsible for serving Zamzam water, so the Prophet (peace and blessings be upon him) granted him permission.
