It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Let none of you wish for death, nor pray for it before it comes to him; for when one of you dies, his deeds are cut off, and the believer's life adds nothing for him but good."
