Salaah Behind An Imaam Who Performs Masah On Cotton Socks

It is not permissible to make Masah on regular cotton socks, as all the conditions of making Masah on Khuffain have not been found. All four Imaams of Fiqh are at a consensus in this matter. Therefore, if the Imaam made Masah on regular cotton socks, his Wudhu is invalid thus rendering his Salaah invalid.

If a person has firm conviction that the Imaam made Masah on his cotton socks and did not wash his feet, he should pray Salaah in another Masjid. If perchance you happened to perform a Salaah behind the Imaam whilst knowing that he had made Masah on regular cotton socks, then you should repeat the Salaah.

It is however the duty of the Imaam to facilitate for all the Muqtadees (followers) by washing his feet and not wiping over his socks if he has Khuffs which do not meet the requirements for the permissibility of making Masah. In this case, the Muqtadees (followers) should approach the Imaam and request him to facilitate for all of them.
