It is narrated from Sayyiduna Anas and Sayyiduna Malik bin Aws bin Hadthan (may Allah be pleased with them) that the Prophet (peace and blessings of Allah be upon him) went out to relieve himself and did not find anyone to accompany him. Sayyiduna Umar (may Allah be pleased with him) followed him carrying water in a jug and found the Prophet (peace and blessings of Allah be upon him) in a state of prostration on a path or platform. So he sat aside behind him until the Prophet (peace and blessings of Allah be upon him) completed his prostration. Then he said: "Umar! You did very well by moving aside when you saw me in a state of prostration. Indeed, Jibreel (peace be upon him) came to me and said: Whoever sends blessings upon you once, Allah will send ten mercies upon him and raise him by ten degrees."
