عَنْ بُرَيْدَةَ الْأَسْلَمِيِّ رَضِيَ اللَّهُ عَنْهُ مِنْ حَدِيثٍ طَوِيلٍ إِنَّ سَلْمَانَ الْفَارِسِيَّ رَضِيَ اللَّهُ عَنْهُ نَظَرَ إِلَى الْخَاتَمِ الَّذِي عَلَى ظَهْرِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَآمَنَ بِهِ وَكَانَ لِلْيَهُودِ فَاشْتَرَاهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِكَذَا وَكَذَا الْحَدِيثَ
It is narrated from Sayyiduna Buraidah Aslami, may Allah be pleased with him, that this is a long hadith, in which it is mentioned that Sayyiduna Salman Farsi, may Allah be pleased with him, saw the Seal of Prophethood on the blessed back of the Messenger of Allah, peace and blessings be upon him, and accepted faith. He was in the possession of the Jews, and the Messenger of Allah, peace and blessings be upon him, had purchased him.
