Sahih al-Bukhari · Book 80: Invocations · Invocation is granted by Allah if impatience is not shown
Narrated Abu Huraira:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، أَخْبَرَنَا مَالِكٌ ، عَنِ ابْنِ شِهَابٍ ، عَنْ أَبِي عُبَيْدٍ ، مَوْلَى ابْنِ أَزْهَرَ عَنْ أَبِي هُرَيْرَةَ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " يُسْتَجَابُ لأَحَدِكُمْ مَا لَمْ يَعْجَلْ يَقُولُ دَعَوْتُ فَلَمْ يُسْتَجَبْ لِي " .
Allah's Messenger (ﷺ) said, "The invocation of anyone of you is granted (by Allah) if he does not show impatience (by saying, "I invoked Allah but my request has not been granted.")
