Narrated 'Amr b. Suh'aib: On his father's authority, said that his grandfather said: The Prophet said in his address while he was leaning against the Ka'bah: (The blood-wit) for each finger is ten camels.
حَدَّثَنَا هُدْبَةُ بْنُ خَالِدٍ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا حُسَيْنٌ الْمُعَلِّمُ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ فِي خُطْبَتِهِ وَهُوَ مُسْنِدٌ ظَهْرَهُ إِلَى الْكَعْبَةِ " فِي الأَصَابِعِ عَشْرٌ عَشْرٌ " .
