The Prophet ﷺ said, "There is no Muslim who makes a supplication free of sin and severing kinship ties except that Allah grants him one of three things. Either his supplication is answered swiftly, or it is stored up for him in the Hereafter, or an equivalent harm is turned away from him."They said, "Then we will make many supplications."He replied, "Allah has even more to give."
حدثنا أبو عامر حدثنا علي عن أبي المتوكل
أن النبي ﷺ قال ما من مسلم يدعو بدعوة ليس فيها إثم ولا قطيعة رحم إلا أعطاه الله بها إحدى ثلاث إما أن تعجل له دعوته وإما أن يدخرها له في الآخرة وإما أن يصرف عنه من السوء مثلها قالوا إذا نكثر قال الله أكثر
Its isnad is hasan, like the one before it, and Abu Amir is Aqdi Abdul-Malik bin Amr mentioned previously. The hadith is found in Tirmidhi 5/566, no. 3573, in the chapter on supplications, where he said, "Hasan sahih gharib," from Ubada bin Samit, and Hakim also graded it sahih in Mustadrak 1/493, and Dhahabi agreed with him.
