Jami` at-Tirmidhi, Book 42, Hadith 8 (In-Book) ⓘ
Narrated 'Amr bin Shu'aib: from his father, from his grandfather, that the Messenger of Allah said: "He is not one of us who resembles other than us, no who resembles the Jews nor the Christians. For indeed greeting of the Jews is pointing the finger, and the greeting of the Christians is waving with the hand."
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا ابْنُ لَهِيعَةَ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لَيْسَ مِنَّا مَنْ تَشَبَّهَ بِغَيْرِنَا لاَ تَشَبَّهُوا بِالْيَهُودِ وَلاَ بِالنَّصَارَى فَإِنَّ تَسْلِيمَ الْيَهُودِ الإِشَارَةُ بِالأَصَابِعِ وَتَسْلِيمَ النَّصَارَى الإِشَارَةُ بِالأَكُفِّ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ إِسْنَادُهُ ضَعِيفٌ . وَرَوَى ابْنُ الْمُبَارَكِ هَذَا الْحَدِيثَ عَنِ ابْنِ لَهِيعَةَ فَلَمْ يَرْفَعْهُ .
