Riyad as-Salihin, 1497

Jabir (May Allah be pleased with him) reported:

The Messenger of Allah (ﷺ) said, "Do not invoke curses on yourself or on your children or on your possessions lest you should happen to do it at a moment when the supplications are accepted, and your prayer might be granted." <b>[Muslim]</b>.

وعن جابر رضي الله عنهما قال‏:‏ قال رسول الله صلى الله عليه وسلم‏:‏ ‏

‏لا تدعوا على أنفسكم، ولا تدعوا على أولادكم، ولا تدعو على أموالكم، لا توافقوا من الله ساعة يسأل فيها عطاء، فيستجيب لكم‏

‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏

<b>Guidance from the Hadith:</b><br> 1) It is forbidden to supplicate against oneself, one’s children, or one’s wealth. This is an aspect of Allah Almighty’s mercy to his slaves.<br> 2) Invoking evil and destruction upon oneself or others is a form of transgression in supplication, while Allah Almighty says: {for He does not like the transgressors.} [Surat al-A‘rāf: 55]
