Takfir (folding the hands) and saying “ameen” after the Fatiha of the Book is not permissible, nor putting the knees upon the ground in the sujud prior to the hands. It is not permissible to do sujud but upon the earth or upon what the earth grows, except for what is eaten or worn. There is no harm with prayer in [clothing with] the hair and soft hair of every [animal] whose meat is eaten. That whose meat is not eaten, then prayer is not permissible in its hair and soft hair except with that for which permission has been specified, and it is prayer in [the hair of] the squirrel, the sable, the fennec fox, and the beaver, and the first (i.e. the better) is that one not pray in it, but one who prays in it his salat is allowed. And as to the foxes, then there is no permission in it except for in the state of taqiyya and exigency.
