" 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)
أَنْ يَجِيءَ الرَّجُلُ مِنْ أَهْلِ الْبَادِيَةِ فَيَسْأَلَ رَسُولَ اللهِ ﷺ فَجَاءَ أَعْرَابِيٌّ فَقَالَ يَا رَسُولَ اللهِ مَتَى قِيَامُ السَّاعَةِ؟ وَأُقِيمَتِ الصَّلَاةُ فَصَلَّى رَسُولُ اللهِ فَلَمَّا فَرَغَ مِنْ صَلَاتِهِ قَالَ أَيْنَ السَّائِلُ عَنِ السَّاعَةِ؟ قَالَ أَنَا يَا رَسُولَ اللهِ قَالَ وَمَا أَعْدَدْتَ لَهَا؟ قَالَ مَا أَعْدَدْتُ لَهَا مِنْ كَبِيرِ عَمَلٍ صَلَاةٍ وَلَا صِيَامٍ إِلَّا أَنِّي أُحِبُّ اللهَ وَرَسُولَهُ فَقَالَ رَسُولُ اللهِ ﷺ الْمَرْءُ مَعَ مَنْ أَحَبَّ قَالَ أَنَسٌ فَمَا رَأَيْتُ الْمُسْلِمِينَ فَرِحُوا بَعْدَ الْإِسْلَامِ بِشَيْءٍ مَا فَرِحُوا بِهِ
