Sayyiduna Habbah and Suwa’, who are the sons of Khalid, say that once we presented ourselves before the Prophet (peace and blessings be upon him) at a time when he was fixing something, but it had tired him. He said to us: As long as your heads can move, never despair of sustenance, because when a person is born by his mother, he is like a chick that has no shell on it, and after that Allah grants him sustenance.
