Jabir bin Abdullah reported,

I heard the Messenger of Allah ﷺ say, "There is no one who makes a supplication but that Allah grants him what he asked for, or wards off from him an equivalent measure of harm, so long as he does not pray for something sinful or for the severing of family ties."

Tirmidhi 3381

عن جابر قال

سمعت رسول الله ﷺ يقول ما من أحد يدعو بدعاء إلا آتاه الله ما سأل أو كف عنه من السوء مثله ما لم يدع بإثم أو قطيعة رحم
