A scholar says that it is not permissible to fold the pants for Salaat.

Answer

There is only one view, namely, it is HARAAM for the pants to be below the ankles at all times, not only during Salaat. The 'mufti maajin' who blurted out his stupid 'fatwa' is not a 'scholar'. He is a moron.

It is absolutely baseless to aver that wearing the pants below the ankles during Salaat is a 'lesser' makruh than wearing the pants folded above the ankles. The pants of a Muslim should not have a fold. But to wear the pants below the ankles cannever be a 'lesser' sin than wearing the pants below the ankles. The warning of Jahannam's fire has been sounded for wearing below the ankles, not so for folded garments. It is grossly wrong to say that the Salaat should be repeated. The fellow who claims that it is Makrooh Tanzeehi to have the pants below the ankles during Salaat appears to be mentally deranged or he is simply a plain moron. The fatwa is baseless. The Hadith does not speak about 'folding of pants' as is being conveyed by the bid'ati who issued the baseless fatwa. It means that the garment, e.g. the jubbah or the shawl, should not be gathered tightly or held in order to prevent it touching the ground when going into Sajdah.
