Being Aware of the Amount of Blood Seen Is Bigger Than the Size of a Dirham
Issue No.741- If a person sees blood on his clothes and is certain that it is less than a dirham (which is almost equal to the upper joint of the forefinger), or it is the blood of a wound or an abscess which does not invalidate the prayer [1], and performs prayer in it and realizes later that the blood is more than a dirham or it is not the blood of a wound or an abscess, his prayer is correct.
