" O Messenger of Allah! When will the Hour be established?" So the Propher ﷺ stood to perform Salat and when he was finished his Salat he said: "Where is the one who asked when the hour will be established?" The man said: "It was I, O Mesenger of Allah!" He said: "What have you prepared for it?" He said: "O Messenger of allah! I have not prepared very much of salat nor fasting for it, but I love Allah and His Messenger." So the Messenger of Allah ﷺ said: "A man shall be with whom ever he loves, and you shall be with whomever you love." So after the advent of Islam, I did not see that anything brought the Muslims more happiness than that. (Using translation from Tirmidhī 2385)
أَنَّ رَجُلًا سَأَلَ رَسُولَ اللهِ ﷺ عَنْ قِيَامِ السَّاعَةِ وَأُقِيمَتِ الصَّلَاةُ فَلَمَّا قَضَى صَلَاتَهُ قَالَ أَيْنَ السَّائِلُ عَنِ السَّاعَةِ؟ قَالَ الرَّجُلُ أَنَا يَا رَسُولَ اللهِ قَالَ مَا أَعْدَدْتَ لَهَا؟ فَإِنَّهَا قَائِمَةٌ قَالَ مَا أَعْدَدْتُ لَهَا كَبِيرَ عَمَلٍ غَيْرَ أَنِّي أُحِبُّ اللهَ وَرَسُولَهُ فَقَالَ رَسُولُ اللهِ ﷺ فَأَنْتَ مَعَ مَنْ أَحْبَبْتَ قَالَ فَمَا فَرِحَ الْمُسْلِمُونَ بِشَيْءٍ بَعْدَ الْإِسْلَامِ مَا فَرِحُوا بِهَذَا الْحَدِيثِ قَالَ فَكَانَ أَنَسٌ يَقُولُ فَنَحْنُ نُحِبُّ اللهَ وَرَسُولَهُ
