Oneness, Uniqueness of Allah (Tawheed)

Bukhari :: Book 9 :: Volume 93 :: Hadith 563

Narrated Abu Qatada:

When the people slept till so late that they did not offer the (morning) prayer, the Prophet said, "Allah captured your souls (made you sleep) when He willed, and returned them (to your bodies) when He willed." So the people got up and went to answer the call of nature, performed ablution, till the sun had risen and it had become white, then the Prophet got up and offered the prayer.
