Sayyiduna Habbah and Sayyiduna Sawa', the sons of Khalid (may Allah be pleased with them both), narrate: We went to the Prophet (peace and blessings be upon him) while he ((peace and blessings be upon him)) was busy with some work, and we helped him. Then he ((peace and blessings be upon him)) said: "Do not despair of provision as long as your heads keep moving, for a person is born by his mother red, without any covering of skin, and then Allah provides for him."
