Majma al-Zawaid — Hadith 3927

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: I heard the Prophet (peace and blessings be upon him) say: "The soul of the believer comes out with sweat, and I do not like a death that is like the death of a donkey." It was asked: "What is the death of a donkey?" The Prophet (peace and blessings be upon him) said: "Sudden death." He said: "And the soul of the disbeliever comes out from the corners of his mouth."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat. Its chain contains Husam bin Misakk, who is da'if (weak).
