Is it permissible to offer Salah

Q: What is the ruling on performing Salah behind an Imam who smokes, shaves his beard, and is a fool who is not qualified to lead people in Jumu`ah (Friday) and congregational Prayers?

(Part No. 7; Page No. 373) A: An Imam, who smokes, shaves his beard and commits sins should be advised and his deeds should be disapproved of. If he does not accept this advice, he must be dismissed from his position if this is possible and will not provoke division among people. Otherwise, it is permissible for whoever finds it easy, to offer Salah (prayer) behind another righteous Imam. Ibn `Umar and others of the Salaf (righteous predecessors) offered Salah behind Al-Hajjaj ibn Yusuf even though he was one of the most unjust people. They did so to consolidate Muslims and avoid the possible division.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
