Reason why the scholars say to make istighfar when making dua is because sins have effect on the dua which causes a delay.

Send salawat upon the prophet ๏ทบ,
Doโฆ
How much of this is down to so many Gazans being killed and how much of it is down to people becoming disinterested or just accepting whatโs happening in Gaza as normal? I said it just a few days ago but itโs upsetting how many of my own mutuals barely mention Gaza anymore.
Shaykh ul-Islaam Ibn Taymeeyah ุฑุญู ู ุงููู said:
โWhoever is accustomed to saying Tasbih [SubhanAllaah - far is Allaah from imperfection] before going to sleep, is given strength and energy in fulfilling his needs and also strength in worshipping.โ
[Majmoo Al-Fatawa, (7/394)]
