Abu Hurayra reported that the Prophet ﷺ said, "No believer turns his face to Allah and asks Him for something but that He gives it to him, either by giving it to him sooner in this world or storing it up for him in the Next World, as long as he does not try to make it come quickly." They asked, "Messenger of Allah, what does 'making it come quickly' mean?" He said, "He says, 'I asked and asked and do not think that I will be answered.'"

حَدَّثَنَا ابْنُ شَيْبَةَ قَالَ: أَخْبَرَنِي ابْنُ أَبِي الْفُدَيْكِ قَالَ: حَدَّثَنِي عُبَيْدُ اللهِ بْنُ مَوْهَبٍ، عَنْ عَمِّهِ عُبَيْدِ اللهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ﷺ قَالَ: مَا مِنْ مُؤْمِنٍ يَنْصُبُ وَجْهَهُ إِلَى اللهِ يَسْأَلُهُ مَسْأَلَةً، إِلاَّ أَعْطَاهُ إِيَّاهَا، إِمَّا عَجَّلَهَا لَهُ فِي الدُّنْيَا، وَإِمَّا ذَخَرَهَا لَهُ فِي الْآخِرَةِ مَا لَمْ يَعْجَلْ، قَالَ: يَا رَسُولَ اللهِ، وَمَا عَجَلَتُهُ؟ قَالَ: يَقُولُ: دَعَوْتُ وَدَعَوْتُ، وَلاَ أُرَاهُ يُسْتَجَابُ لِي.
