Narrated Ibn 'Umar:
حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ ، أَخْبَرَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ ، عَنِ ابْنِ عُمَرَ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ الْيَهُودَ إِذَا سَلَّمَ عَلَيْكُمْ أَحَدُهُمْ فَإِنَّمَا يَقُولُ السَّامُ عَلَيْكُمْ فَقُلْ عَلَيْكَ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
That the Messenger of Allah (ﷺ) said: "Indeed when a Jew gives Salam to one of you, then he is only saying: 'As-Samu 'Alaikum' (Death be upon you) so say: "Alaik (And upon you).'" [Abu 'Eisa said:] This Hadith is Hasan Sahih.
