حَدَّثَنَا يَحْيَى بْنُ حَسَّانَ ، أَنْبأَنَا ابْنُ عُيَيْنَةَ ، عَنْ سَالِمٍ أَبِي النَّضْرِ ، عَنْ بُسْرِ بْنِ سَعِيدٍ ، قَالَ : أَرْسَلَنِي أَبُو جُهَيْمٍ الْأَنْصَارِيُّ إِلَى زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ أَسْأَلُهُ مَا سَمِعَ مِنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الَّذِي يَمُرُّ بَيْنَ يَدَيْ الْمُصَلِّي، فَقَالَ : إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ :" لَأَنْ يَقُومَ أَحَدُكُمْ أَرْبَعِينَ، خَيْرٌ لَهُ مِنْ أَنْ يَمُرَّ بَيْنَ يَدَيْ الْمُصَلِّي ".
قَالَ : فَلَا أَدْرِي سَنَةً أَوْ شَهْرًا أَوْ يَوْمًا

Yahya bin Hassan told us, Ibn Uyaynah told us, on the authority of Salim Abi Al-Nadr, on the authority of Busr bin Saeed, he said: Abu Juhaym sent me Al-Ansari to Zayd bin Khaled Al-Juhani, ask him what he heard from the Prophet, may God bless him and grant him peace, regarding what passes in front of the praying person. He said: The Messenger of God, may God bless him and grant him peace, said: God, may God bless him and grant him peace, said: “For one of you to stand for forty days, it is better for him than to pass in front of a person praying.”
He said: I do not know a year, a month, or a day.
