Abu Hurayra reported that the Messenger of Allah ﷺ said, "The supplication of any of you is answered as long as he does not make supplication for something which is a wrong action or cutting off ties of kinship or become impatient and say, 'I made supplication and was not answered,' and so he stops making supplication.'"

حَدَّثَنَا عَبْدُ اللهِ، قَالَ: حَدَّثَنَا مُعَاوِيَةُ، أَنَّ رَبِيعَةَ بْنَ يَزِيدَ حَدَّثَهُ، عَنْ أَبِي إِدْرِيسَ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ﷺ قَالَ: يُسْتَجَابُ لأَحَدِكُمْ مَا لَمْ يَدْعُ بِإِثْمٍ أَوْ قَطِيعَةِ رَحِمٍ، أَوْ يَسْتَعْجِلَ فَيَقُولُ: دَعَوْتُ فَلاَ أَرَى يَسْتَجِيبُ لِي، فَيَدَعُ الدُّعَاءَ.
