There is agreement that what invalidates it is all invalidating ablution, and it will be covered in this section later. The scholars differed regarding removing the socks. Whether it invalidates purity or not. Some say that purity is invalidated and ablution is resumed, and some say that the purity of the feet is invalidated in particular by washing them, and based on the above there must be disagreement in Loyalty and who says that removing the sandals does not affect the purity of the feet? This is what I say, but if he resumes ablution, it is more prudent and does not affect his entire purity unless something happens that invalidates it, as will follow.
