What is the ruling on crying out loud in such a way that it is mistaken for laughter, not crying?

The basic ruling regarding weeping is that it is permissible, even with sound, as long as it is not accompanied by wailing (niyāḥah) or any forbidden act. What is forbidden is wailing, not weeping.

Permissible weeping is that which stems from tenderness or awe of Allah. It becomes disliked (makrūh) or forbidden (ḥarām) if it is an expression of impatience (jazaʿ) and a lack of submission to divine decree.

An exception is made for weeping that overwhelms a person, or that is out of love and tenderness, such as weeping over a child. As for weeping over the knowledge and righteousness of the deceased that has passed, its recommendation appears evident. However, weeping over a loss of their good deeds (birr) and worldly affairs seems disliked. As for mere tearing of the eyes, there is no objection to it.
