It was narrated from Abu Hurairah that the Messenger of Allah (S.A.W) said:"If the people knew what (virtue) there is in the call to prayer and the first row, and they had no other way but to draw lots concerning them, they would draw lots. If they knew what (virtue) there is in coming early for the prayer, they would compete in doing so. And if they knew what (virtue) there is in 'Atamah and Subh prayer, they would come even if they had to crawl."
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ سُمَىٍّ، عَنْ أَبِي صَالِحٍ، 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 عَلَيْهِ وَلَوْ يَعْلَمُونَ مَا فِي التَّهْجِيرِ لاَسْتَبَقُوا إِلَيْهِ وَلَوْ عَلِمُوا مَا فِي الْعَتَمَةِ وَالصُّبْحِ لأَتَوْهُمَا وَلَوْ حَبْوًا " .
