The World Federation One Stop Fiqh

Ruling 155

If an object becomes impure with the urine of a breast feeding boy or a girl who has not started weaning, in the event that some water, however little, is poured over it once so that it reaches the whole of the impure area, it becomes pure. However, the recommended precaution is that water should be poured over it a second time. In the case of clothing, rugs, and similar things, wringing is not necessary.

The area to be wiped must be dry; and if it is wet to the extent that the wetness of the hand has no effect on it, the wiping is invalid. However, there is no problem if the area to be wiped is merely damp, or its wetness is so little that it becomes absorbed in the wetness of the hand.
