صحيح مسلم#981Sahihحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرٍ عَنْ أَبِي صَالِحٍ السَّمَّانِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لَوْ يَعْلَمُ النَّاسُ مَا فِي النِّدَاءِ وَالصَّفِّ الأَوَّلِ ثُمَّ لَمْ يَجِدُوا إِلاَّ أَنْ يَسْتَهِمُوا عَلَيْهِ لاَسْتَهَمُوا وَلَوْ يَعْلَمُونَ مَا فِي التَّهْجِيرِ لاَسْتَبَقُوا إِلَيْهِ وَلَوْ يَعْلَمُونَ مَا فِي الْعَتَمَةِ وَالصُّبْحِ لأَتَوْهُمَا وَلَوْ حَبْوًا " .
Abu Huraira reported:The Messenger of Allah (ﷺ) said: If the people were to know what excellence is there in the Adhan and in the first row, and they could not (get these opportunities) except by drawing lots, they would have definitely done that. And if they were to know what excellence lies in joining the prayer in the first takbir (prayer), they would have vied with one another. And if they were to know what excellence lies in the night prayer and morning prayer, they would have definitely come even if crawling (on their knees)
