Answer:
(Fatwa: 509/434/B=1433)
The imam who does not wash his feet in wudhu and instead does masah over cotton socks, his wudhu and salah are not valid. Qadiyanis are kafir and apostate, salah is not valid behind them. The imam who does not believe in Hadith is also nearly kafir. Salah is not valid behind all the trio, i.e. salah shall not be valid behind them. In such compulsion, you may offer salah behind the imam who is only bidati, your salah behind him shall be valid but makrooh. You shall get the reward and virtues of jama’ah.
