I have a question regarding congretional dua after every fard prayer and collective dua. Is it biddah or what. please clarify.
Answer
(Fatwa: 1319/1238=D/1429)
Supplicating after performing obligatory salah is proved by the Hadith and it is also narrated that the supplication is a virtuous thing. The people should supplicate individually; however it is not wrong if it looks like congregational. If someone ends the prayer earlier while the other prays a bit longer, it is also not wrong, it is allowed. By ?congregational? if you mean some other method, then you should explain it.
