Likewise, touching a beardless youth with desire, so long as no barrier intervenes, nullifies ablution; it does not do so for the one who is touched, even if he experiences arousal. Ablution is also broken by washing a corpse and by eating nothing but the meat of a camel.

“Every matter that obliges a full ritual bath likewise obliges ablution—except death.”

If a person is certain of purity yet doubts whether he has fallen into a state of impurity, or the reverse, he acts on what is certain. Should he be sure that both states have occurred but not know which came first, he assumes the opposite of whichever state he was in before the two events took place.

It is forbidden for someone in a state of minor impurity to touch a mushaf, perform the prayer, or circumambulate the Kaʿbah.
