Hammam said:

Hudhaifah led the people in prayer in al-Mada’in standing on the shop(or a bench). Abu Mas’ud took him by his shirt, and brought him down. When he( Abu Mas’ud) finished his prayer, he said: Do you not know that they(the people) were prohibited to do so. He said: Yes, I remembered when you pulled me down.

حَدَّثَنَا أَحْمَدُ بْنُ سِنَانٍ، وَأَحْمَدُ بْنُ الْفُرَاتِ أَبُو مَسْعُودٍ الرَّازِيُّ، - الْمَعْنَى - قَالاَ حَدَّثَنَا يَعْلَى، حَدَّثَنَا الأَعْمَشُ، عَنْ إِبْرَاهِيمَ، عَنْ هَمَّامٍ، أَنَّ حُذَيْفَةَ أَمَّ النَّاسَ، بِالْمَدَائِنِ عَلَى دُكَّانٍ فَأَخَذَ أَبُو مَسْعُودٍ بِقَمِيصِهِ فَجَبَذَهُ فَلَمَّا فَرَغَ مِنْ صَلاَتِهِ قَالَ أَلَمْ تَعْلَمْ أَنَّهُمْ كَانُوا يُنْهَوْنَ عَنْ ذَلِكَ قَالَ بَلَى قَدْ ذَكَرْتُ حِينَ مَدَدْتَنِي .
