أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَخْبَرَنِي يَحْيَى بْنُ سَعِيدٍ، عَنِ ابْنِ عَجْلاَنَ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى عَنِ التَّحَلُّقِ يَوْمَ الْجُمُعَةِ قَبْلَ الصَّلاَةِ وَعَنِ الشِّرَاءِ وَالْبَيْعِ فِي الْمَسْجِدِ .
