سَمِعَ مِنْ رَسُولِ اللَّهِ ﷺ فِي الْمَارِّ بَيْنَ يَدَىِ الْمُصَلِّي قَالَ أَبُو جُهَيْمٍ قَالَ رَسُولُ اللَّهِ ﷺ لَوْ يَعْلَمُ الْمَارُّ بَيْنَ يَدَىِ الْمُصَلِّي مَاذَا عَلَيْهِ لَكَانَ أَنْ يَقِفَ أَرْبَعِينَ خَيْرًا لَهُ مِنْ أَنْ يَمُرَّ بَيْنَ يَدَيْهِ قَالَ أَبُو النَّضْرِ لاَ أَدْرِي قَالَ أَرْبَعِينَ يَوْمًا أَوْ شَهْرًا أَوْ سَنَةً
