Narrated Anas bin Malik:
حَدَّثَنِي إِسْحَاقُ ، أَخْبَرَنَا حَبَّانُ ، حَدَّثَنَا هَمَّامٌ ، حَدَّثَنَا قَتَادَةُ ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ ، أَنَّ يَهُودِيًّا، رَضَّ رَأْسَ جَارِيَةٍ بَيْنَ حَجَرَيْنِ، فَقِيلَ لَهَا مَنْ فَعَلَ بِكِ هَذَا أَفُلاَنٌ أَفُلاَنٌ حَتَّى سُمِّيَ الْيَهُودِيُّ فَأَوْمَأَتْ بِرَأْسِهَا، فَجِيءَ بِالْيَهُودِيِّ فَاعْتَرَفَ، فَأَمَرَ بِهِ النَّبِيُّ صلى الله عليه وسلم فَرُضَّ رَأْسُهُ بِالْحِجَارَةِ. وَقَدْ قَالَ هَمَّامٌ بِحَجَرَيْنِ .
A Jew crushed the head of a girl between two stones. It was said to her. "Who has done this to you, such-and-such person, such-and-such person?" When the name of the Jew was mentioned, she nodded with her head, agreeing. So the Jew was brought and he confessed. The Prophet (ﷺ) ordered that his head be crushed with the stones. (Hammam said, "with two stones.")
