أَنَّ أَبَا بَكْرَةَ جَاءَ وَرَسُولُ اللَّهِ رَاكِعٌ فَرَكَعَ دُونَ الصَّفِّ ثُمَّ مَشَى إِلَى الصَّفِّ فَلَمَّا قَضَى النَّبِيُّ ﷺ صَلاَتَهُ قَالَ أَيُّكُمُ الَّذِي رَكَعَ دُونَ الصَّفِّ ثُمَّ مَشَى إِلَى الصَّفِّ فَقَالَ أَبُو بَكْرَةَ أَنَا فَقَالَ النَّبِيُّ ﷺ زَادَكَ اللَّهُ حِرْصًا وَلاَ تَعُدْ
