from Abu Tamimah al-Hujaimi from Jabir bin Sulaim who said: "I went to the Prophet ﷺ and I said: ''Alaikas-Salam (upon you be peace)' so he replied: 'Do not say "'Alaikas-Salam" rather say As-Salamu Alaik.'" And he mentioned the story in its entirety.  

الترمذي:٢٧٢٢حَدَّثَنَا بِذَلِكَ الْحَسَنُ بْنُ عَلِيٍّ الْخَلاَّلُ حَدَّثَنَا أَبُو أُسَامَةَ عَنْ أَبِي غِفَارٍ الْمُثَنَّى بْنِ سَعِيدٍ الطَّائِيِّ عَنْ أَبِي تَمِيمَةَ الْهُجَيْمِيِّ عَنْ جَابِرِ بْنِ سُلَيْمٍ قَالَ

أَتَيْتُ النَّبِيَّ ﷺ فَقُلْتُ عَلَيْكَ السَّلاَمُ فَقَالَ لاَ تَقُلْ عَلَيْكَ السَّلاَمُ وَلَكِنْ قُلِ السَّلاَمُ عَلَيْكَ وَذَكَرَ قِصَّةً طَوِيلَةً وَهَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ

I came to the Prophet ﷺ and said: Upon you be peace, Messenger of Allah! He said: Do not say: Upon you be peace, for "Upon you be peace" is the salutation to the dead.  

أبو داود:٥٢٠٩حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا أَبُو خَالِدٍ الأَحْمَرُ عَنْ أَبِي غِفَارٍ عَنْ أَبِي تَمِيمَةَ الْهُجَيْمِيِّ عَنْ أَبِي جُرَىٍّ الْهُجَيْمِيِّ قَالَ

أَتَيْتُ النَّبِيَّ ﷺ فَقُلْتُ عَلَيْكَ السَّلاَمُ يَا رَسُولَ اللَّهِ قَالَ لاَ تَقُلْ عَلَيْكَ السَّلاَمُ فَإِنَّ عَلَيْكَ السَّلاَمُ تَحِيَّةُ الْمَوْتَى
