Quran 39.42-43
Allah receiveth (men's) souls at the time of their death, and that (soul) which dieth not (yet) in its sleep. He keepeth that (soul) for which He hath ordained death and dismisseth the rest till an appointed term. Lo! herein verily are portents for people who take thought. Or choose they intercessors other than Allah? Say: What! Even though they have power over nothing and have no intelligence?
