Is it permissible to play pranks on siblings and secretly take their belongings for fun, and has anything been reported from Ibn Hajar regarding this?

The author did not find what the questioner attributed to Ibn Hajar concerning the permissibility of joking in the manner mentioned. He rather stated the controls for permissible jesting in Fath al-Bari, which is that it should not involve excess or continuous engagement that distracts from the remembrance of Allah and leads to hardness of heart and loss of awe. He pointed out that terrifying a Muslim by taking his property and hiding it, even as a joke, is forbidden, citing evidence from the Sunnah and interpretive works such as Nayl al-Awtar by Al-Shawkani, Fayd al-Qadir by Al-Manawi, and Sharh Mushkil al-Athar by Al-Tahawi, all of which affirm the impermissibility of terrifying a Muslim even in jest.
