The Prophet ﷺ said, "There is no Muslim who makes a supplication that contains no sin or severing of family ties except that Allah grants him one of three things in return. Either his supplication is answered swiftly, or it is stored for him in the Hereafter, or an equivalent harm is turned away from him."The companions said, "Then we will ask abundantly."He replied, "Allah is more abundant still."
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.
Ahmad narrated it (11133), and Bukhari in Adab al-Mufrad (710), and Hakim (1/493), all of them through routes from Ali bin Ali Rifai, who said, I heard Abu Mutawakkil Naji say, Abu Saeed Khudri said, from the Prophet ﷺ and he mentioned it. Its isnad is hasan because of Ali bin Ali Rifai, for his hadith is hasan.Hakim said, "This is a hadith sahih in isnad."
