It says in al-Rawḍ: “and one who dresses in a manner that invites ridicule.” This exists and is common—for example, a man who puts horns on his head, or wings on his right and left. I think this is found in what are called cartoon films.
It says: “nor one who eats in the marketplace,” except in places designated for eating, such as restaurants. It says: “except for something slight, such as a morsel or an apple.” There is nothing wrong with this, although in truth, by our standards it would compromise his propriety. If you were walking to the mosque with an apple, eating it in front of people, it might be said: “This man has gone mad.” But if it is in a restaurant, this is not considered contrary to propriety.
It says: “nor one who stretches out his leg in a gathering of people, or sleeps among those who are seated, and the like.” But in other books they say that whoever departs from the usual manner of sitting compromises his propriety.
Whenever the impediments cease: if the child reaches maturity, the insane person regains his reason, the disbeliever embraces Islam, or the openly sinful person repents, their testimony is accepted.
His statement, “Whenever the impediments cease: if the child reaches maturity, the insane person regains his reason, the disbeliever embraces Islam, or the openly sinful person repents, their testimony is accepted”: the preceding conditions are considered only at the time testimony is given. Thus, if a child reaches maturity after having witnessed the matter while still young, his testimony is accepted. What is required at the time of witnessing, with respect to this condition, is discernment; maturity is a condition for giving testimony. Thus, a child witnessed an event when he was ten years old and accurately retained it, but did not give testimony until after reaching maturity—having reached it through the growth of pubic hair at the age of twelve—his testimony is accepted.
His statement, “and the insane person regains his reason”: but sound reason is a condition both for witnessing and for giving testimony. So how can he say, “the insane person regains his reason”?
