Musannaf Ibn Abi Shaybah

Hazrat Abdur Rahman bin Abi Laila (may Allah have mercy on him) narrates that while a group of the companions was present with the Noble Prophet (peace and blessings be upon him), the Prophet (peace be upon him) sent a message to his wives for food, but none of his wives had anything to eat. Suddenly, Hazrat Ali (may Allah be pleased with him) appeared from the front, covered in dust and in a disheveled state, with nearly a sa’ (a measure) of dates on his shoulder, which he had earned through labor. The Noble Prophet (peace and blessings be upon him) said: "Welcome to the one who carries the burden and to the burden he carries." Then he (peace be upon him) seated him near himself and brushed the dust from his head, then said: "Welcome, O Abu Turab!" Then he brought the dates close, until everyone ate to their fill. Then the Prophet (peace and blessings be upon him) sent a portion of it to all his pure wives as well.
