حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي النَّضْرِ، عَنْ بُسْرِ بْنِ سَعِيدٍ، أَنَّ زَيْدَ بْنَ خَالِدٍ الْجُهَنِيَّ، أَرْسَلَهُ إِلَى أَبِي جُهَيْمٍ يَسْأَلُهُ مَاذَا سَمِعَ مِنْ، رَسُولِ اللَّهِ صلى الله عليه وسلم فِي الْمَارِّ بَيْنَ يَدَىِ الْمُصَلِّي قَالَ أَبُو جُهَيْمٍ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم "
لَوْ يَعْلَمُ الْمَارُّ بَيْنَ يَدَىِ الْمُصَلِّي مَاذَا عَلَيْهِ لَكَانَ أَنْ يَقِفَ أَرْبَعِينَ خَيْرًا لَهُ مِنْ أَنْ يَمُرَّ بَيْنَ يَدَيْهِ "
Abu Juhaym ibn al-Hārith ibn As-Simmah al-Ansāri (may Allah be pleased with him) reported directly from the Messenger of Allah (may Allah's peace and blessings be upon him) that he said: "If the one passing in front of a person who is praying would know the gravity of his sin, it would have been better for him to stand for forty than to pass in front him." Abu An-Nadr said: "I am not sure if he said forty days, months, or years."
