Al-Adab Al-Mufrad, Hadith 1103 ⓘ
Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "Do not give the People of the Book the greeting first. Force them to the narrowest part of the road."
حَدَّثَنَا مُوسَى، قَالَ: حَدَّثَنَا وُهَيْبٌ، قَالَ: حَدَّثَنَا سُهَيْلٌ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: أَهْلُ الْكِتَابِ لاَ تَبْدَأُوهُمْ بِالسَّلاَمِ، وَاضْطَرُّوهُمْ إِلَى أَضْيَقِ الطَّرِيقِ.
