All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
We have already issued Fataawa 89102 and 92220 clarifying the excellence of dying on Friday, so please refer to them.
However, after a great effort and investigation, we have not come across any evidence on the excellence of dying on the day of 'Eed or on the 15th of Sha'baan or in any other days.
If a person dies while Allaah is pleased with him, it does not matter on which day he died. Similarly, if a person dies on a preferred day while Allaah is angry with him, then that day does not intercede for him.
