What is the ruling on the Dua after Salaah. That is the recitation of aloud Dua.

To make Du'a in any form (loudly, softly, collectively, etc.) and any time (before, after Fardh Salaat, etc.) is permissible. While there are substantiations for the different forms and times of making Du'a, Shari'ah does not restrict the making of Du'a in those forms or times not specifically substantiated in Shari'ah. At most, making Du'a is permissible and an act of great virtue and merit. It is not permissible to project a permissible act as compulsory as this is projecting a wrong view of the Shari'ah, thus, causing distortion of Deen.

To regard the collective Du'a after Fardh Salaat or Sunnah Salaat as compulsory will be Bid'ah as that projects the incorrect image of Shari'ah.

Loud Du'aa after Salaat is established and proven by many Ahaadith. It is narrated that Rasulullah (Sallallaahu Alayhi Wasallam) should say after Fajr Salaat, 'O Allah, I ask you for beneficial knowledge, accepted actions and pure sustenance.'

In another Hadith, Rasulullah (Sallallaahu Alayhi Wasallam) told Mu'aadh ibn Jabal (Radhiallaahu Anhu), 'I love you, so say after every Salaat, 'O Allah assist me in your rememberance and gratefulness.' (Fataawa Mahmoodiyah vol.10 pg.238)
