Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "Allah Almighty is more reluctant over the death of His believing servant than any one of you is over his finest wealth, until He takes his soul upon his bed."
Al-Bazzar recorded it; its chain contains a narrator, Abd al-Rahman bin Ziyad bin An'um, whom Imam Ahmad and most people declared da'if (weak), though some preferred him over Ibn Lahi'ah.
