" لاَ يَتَمَنَّيَنَّ أَحَدٌ مِنْكُمُ الْمَوْتَ إِمَّا مُحْسِنًا فَلَعَلَّهُ أَنْ يَزْدَادَ خَيْرًا وَإِمَّا مُسِيئًا فَلَعَلَّهُ أَنْ يَسْتَعْتِبَ "
It was narrated from Abu Hurairah that the Messenger of Allah said: "None of you should wish for death. Either he is a doer of good, so perhaps he may do more good, or he is an evildoer but perhaps he will give up his evil ways."
