Passing in front of someone who is performing Prayer

Busr bin Sa’eed said:
“They sent me to Zaid bin Khalid to ask him about passing in front of one who is performing prayer. He told me that the Prophet ﷺ said: ‘Waiting for forty is better than passing in front of one who is performing prayer.’”
(One of the narrators) Sufyan said: "I do not know if he meant forty years, months, days, or hours."

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ سَالِمٍ أَبِي النَّضْرِ، عَنْ بُسْرِ بْنِ سَعِيدٍ، قَالَ أَرْسَلُونِي إِلَى زَيْدِ بْنِ خَالِدٍ أَسْأَلُهُ عَنِ الْمُرُورِ، بَيْنَ يَدَىِ الْمُصَلِّي فَأَخْبَرَنِي عَنِ النَّبِيِّ ﷺ قَالَ " لأَنْ يَقُومَ أَرْبَعِينَ خَيْرٌ لَهُ مِنْ أَنْ يَمُرَّ بَيْنَ يَدَيْهِ " . قَالَ سُفْيَانُ فَلاَ أَدْرِي أَرْبَعِينَ سَنَةً أَوْ شَهْرًا أَوْ صَبَاحًا أَوْ سَاعَةً .

It was narrated from Busr bin Sa’eed that Zaid bin Khalid sent word to Abu Juhaim Al-Ansari asking him:
“What did you hear from the Prophet ﷺ about a man when he is performing prayer?” He said: “I heard the Prophet ﷺ saying: ‘If anyone of you knew (how great is the sin involved) when he passed in front of his brother who is performing prayer, then waiting for forty’,” (one of the narrators) said: “I do not know if he meant forty years, forty months, or forty days, ‘would be better for him than that.”

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، عَنْ سَالِمٍ أَبِي النَّضْرِ، عَنْ بُسْرِ بْنِ سَعِيدٍ، أَنَّ زَيْدَ بْنَ خَالِدٍ، أَرْسَلَ إِلَى أَبِي جُهَيْمٍ الأَنْصَارِيِّ يَسْأَلُهُ مَا سَمِعْتَ مِنَ النَّبِيِّ، ﷺ فِي الرَّجُلِ يَمُرُّ بَيْنَ يَدَىِ الرَّجُلِ وَهُوَ يُصَلِّي فَقَالَ سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ " لَوْ يَعْلَمُ أَحَدُكُمْ مَالَهُ أَنْ يَمُرَّ بَيْنَ يَدَىْ أَخِيهِ وَهُوَ يُصَلِّي كَانَ لأَنْ يَقِفَ أَرْبَعِينَ - قَالَ لاَ أَدْرِي أَرْبَعِينَ عَامًا أَوْ أَرْبَعِينَ شَهْرًا أَوْ أَرْبَعِينَ يَوْمًا - خَيْرٌ لَهُ مِنْ ذَلِكَ " .
