It is narrated from Ata bin Abi Rabah that Sayyiduna Umar bin Khattab, may Allah be pleased with him, said to Ya'la bin Munabbih, who used to pour water when Sayyiduna Umar, may Allah be pleased with him, performed ghusl: "Pour water on my head." Ya'la said: "Do you want the sin to be upon me? If you command, I will pour." Sayyiduna Umar, may Allah be pleased with him, said: "Pour, for nothing will happen by pouring water except that Sayyiduna Bilal, may Allah be pleased with him, will be even more troubled."
