It was narrated from Abu Hurairah that :
the Messenger of Allah ﷺ said: "It is necessary that you do not become hasty." It was said: "What does being hasty mean, O Messenger of Allah?" He said: "When one says: 'I supplicated to Allah but Allah did not answer me.'"

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا إِسْحَاقُ بْنُ سُلَيْمَانَ، عَنْ مَالِكِ بْنِ أَنَسٍ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي عُبَيْدٍ، مَوْلَى عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " يُسْتَجَابُ لأَحَدِكُمْ مَا لَمْ يَعْجَلْ " . قِيلَ وَكَيْفَ يَعْجَلُ يَا رَسُولَ اللَّهِ قَالَ " يَقُولُ قَدْ دَعَوْتُ اللَّهَ فَلَمْ يَسْتَجِبِ اللَّهُ لِي " .
