حَدَّثَنَا عَمْرُو بْنُ عَاصِمٍ، قَالَ: حَدَّثَنَا هَمَّامٌ، قَالَ: حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسٍ
قَالَ: مَرَّ يَهُودِيٌّ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: السَّامُ عَلَيْكُمْ، فَرَدَّ أَصْحَابُهُ السَّلَامَ، فَقَالَ: قَالَ: السَّامُ عَلَيْكُمْ، فَأُخِذَ الْيَهُودِيُّ فَاعْتَرَفَ، قَالَ: رُدُّوا عَلَيْهِ مَا قَالَ
“A Jew passed by the Prophet (sallallahu alayhi wa sallam), may Allah bless him and grant him peace, saying, ‘Peace be upon you.’ His Companions returned the salam.” The Prophet (sallallahu alayhi wa sallam) said, ‘The Jew said, ‘Poison (sam) be upon you.’ He caught hold of the Jew who admitted it.’ The Prophet (sallallahu alayhi wa sallam) said, ‘Answer him with what he said.’
