A local qaari told a hafiz who had folded his trousers above his ankles that it is haraam to have the trousers folded up in Salaat.

Answer

The local qari displays a queer mentality. He should rather say and tell the hafiz that it is haraam at all times to wear a trousers which is below the ankles. When the hafiz commits the haraam act of unfolding his trousers after Salaat, then the qari adopts silence, and when he rectifies his haraam act by folding up the trousers, then the qari objects. His mind operates in reverse order.
