وَإِنْ قَصَّ خَمْسَةَ أَظَافِيرَ مُتَفَرِّقَةً مِنْ يَدَيْهِ وَرِجْلَيْهِ فَعَلَيْهِ صَدَقَةٌ عِنْدَهُمَا، وَقَالَ مُحَمَّدٌ: عَلَيْهِ دَمٌ
Translation: If he clips five nails distributed among his hands and feet, Abu Hanifah and Abu Yusuf require charity, whereas Muhammad requires an animal offering.
Mutafarriqatan means distributed over different hands/feet, rather than all belonging to one complete hand or foot. ʿIndahuma here refers to Abu Hanifah and Abu Yusuf.
It would be inaccurate to say that five nails always incur dam. A complete set on one hand and a dispersed set have different analysis, and the dispersed set carries an explicit juristic disagreement.
