It is narrated from Sayyiduna Ibn Amr, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: "The most beloved way of fasting to Allah is that of Sayyiduna Dawud, peace be upon him. He used to fast every alternate day. Similarly, his prayer is the most beloved to Allah. He would sleep for half the night, stand in prayer for a third of it, and rest for a sixth of it."
