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) and he ((peace and blessings be upon him)) said: "Do not, both of you, 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, the Mighty and Majestic, provides for him."
