الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ أَحْمَدَ بْنِ إِسْحَاقَ عَنْ سَعْدَانَ بْنِ مُسْلِمٍ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) اكْنُسُوا أَفْنِيَتَكُمْ وَ لَا تَشَبَّهُوا بِالْيَهُودِ .
5. Al-Husayn ibn Muhammad has narrated from Ahmad ibn Ishaq from Sa‘dan ibn Muslim from Ishaq ibn ‘Ammar who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘You must sweep the yard of your house and do not become similar to the Jews.’”
