The ruling on praying behind an imam who lets his garment hang below the ankles

Question:
This questioner asks, Honorable Shaykh, about the ruling on praying behind an imam who lets his garment hang below the ankles. Is our prayer valid?

Answer:
Do not abandon the congregational prayer, and you must advise this imam. As for abandoning the congregational prayer because you say the imam is letting his garment hang, yes, the imam is wrong and is doing something forbidden, but do not abandon the congregational prayer. Pray with them and advise the imam if you see him letting his garment hang. But what is letting the garment hang? Letting the garment hang is when it goes below the ankles; that is letting the garment hang. Because some people consider anything that goes below the middle of the leg to be letting the garment hang, and that is a mistake. Yes.
