"The Messenger of Allah ﷺ performed Salat, making it long. They said: 'O Messenger of Allah! You have performed Salat (in a manner) which you do not ordinarily perform it.' He said: 'Yes, It was a prayer of hope and fear. In it I asked Allah for three things. He granted me two, and withheld one from me. I asked him that my Ummah not be destroyed by drought. He granted that. I asked him that they not be overcome by enemies from other then them. He granted that. And I asked him that some of them not suffer from the harm of others, and He withheld that."' (Using translation from Tirmidhī 2175)
صَلَّى رَسُولُ اللهِ ﷺ صَلَاةً فَأَطَالَهَا فَقَالُوا يَا رَسُولَ اللهِ صَلَّيْتَ صَلَاةً لَمْ تَكُنْ تُصَلِّيهَا قَالَ «أَجَلْ إِنَّهَا صَلَاةُ رَغَبٍ وَرَهَبٍ وَإِنِّي سَأَلْتُ رَبِّي فِيهَا ثَلَاثًا فَأَعْطَانِي اثْنَتَيْنِ وَمَنَعَنِي وَاحِدَةً سَأَلْتُهُ أَنْ لَا يُهْلِكَ أُمَّتِي بِسُنَّةٍ فَأَعْطَانِيهَا وَسَأَلْتُهُ أَلَّا يُسَلِّطَ عَلَيْهِمْ عَدُوًّا مِنْ غَيْرِهِمْ فَأَعْطَانِيهَا وَسَأَلْتُهُ أَنْ لَا يُذِيقَ بَعْضَهُمْ بَأْسَ بَعْضٍ فَمَنَعَنِيهَا»
