Hammam’s version has the words “He took out the blood by pressing with his fingers”. Abu Dawud said this tradition has been narrated by the people of Basrah who alone are its transmitters.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، بِهَذَا الْحَدِيثِ بِمَعْنَى أَبِي الْوَلِيدِ قَالَ ثُمَّ سَلَتَ الدَّمَ بِيَدِهِ ‏.‏ قَالَ أَبُو دَاوُدَ رَوَاهُ هَمَّامٌ قَالَ سَلَتَ الدَّمَ عَنْهَا بِإِصْبَعِهِ ‏.‏ قَالَ أَبُو دَاوُدَ هَذَا مِنْ سُنَنِ أَهْلِ الْبَصْرَةِ الَّذِي تَفَرَّدُوا بِهِ ‏.‏
