Sunan Abi Dawud 5205
Narrated AbuHurayrah:
Suhayl ibn AbuSalih said: I went out with my father to Syria. The people passed by the cloisters in which there were Christians and began to salute them. My father said: Do not give them salutation first, for AbuHurayrah reported the Messenger of Allah (ﷺ) as saying: Do not salute them (Jews and Christians) first, and when you meet them on the road, force them to go to the narrowest part of it.
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، قَالَ خَرَجْتُ مَعَ أَبِي إِلَى الشَّامِ فَجَعَلُوا يَمُرُّونَ بِصَوَامِعَ فِيهَا نَصَارَى فَيُسَلِّمُونَ عَلَيْهِمْ فَقَالَ أَبِي لاَ تَبْدَءُوهُمْ بِالسَّلاَمِ فَإِنَّ أَبَا هُرَيْرَةَ حَدَّثَنَا عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ ‏
"‏ لاَ تَبْدَءُوهُمْ بِالسَّلاَمِ وَإِذَا لَقِيتُمُوهُمْ فِي الطَّرِيقِ فَاضْطَرُّوهُمْ إِلَى أَضْيَقِ الطَّرِيقِ ‏"‏ ‏.‏
