Mukhtasar Bukhari (Abridged) 1958 — Wishing for death is forbidden

Narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) used to say: "Every person should never wish for death because of distress or calamity, and if someone is compelled to do so, then he should pray in this way: 'O Allah! Keep me alive as long as life is better for me, and when death is better for me, then take me away.'"
