(2) I heard that somebody is saying Deoband has given Fatwa that salah behind a Barailavi who used to say ‘YAA RASULULLAH’ is valid and the muqtadi can get reward. Alhamdulillah, I am Deobandi, if so can I get my individual reward while offering prayer behind Barailavi? Please reply as soon as possible and I will show this answer to my relatives so that I can warn them.
بسم الله الرحمن الرحيم
(1) If the beliefs of a Bida’ati have not reached to the extent of kufr then salah is valid behind him but it shall be makrooh. Hence you should not offer salah behind him. You should offer salah behind any pious imam in any other mosque.
(2) See answer no. 1.
Allah knows Best!
