عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ اللَّهِ عَنْ عَلِيِّ بْنِ الرَّيَّانِ بْنِ الصَّلْتِ عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ الْوَاسِطِيِّ عَنْ وَاصِلِ بْنِ سُلَيْمَانَ عَنْ دُرُسْتَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ ذَكَرْنَا الرُّءُوسَ مِنَ الشَّاةِ فَقَالَ الرَّأْسُ مَوْضِعُ الذَّكَاةِ وَ أَقْرَبُ مِنَ الْمَرْعَى وَ أَبْعَدُ مِنَ الْأَذَى .
5. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from Ali ibn al-Rayyan ibn al-Salt from ‘Ubayd Allah ibn ‘Abd Allah al-Wasitiy from Wasil ibn Sulayman from Durust who has said the following: “We once mentioned heads of sheep before abu ‘Abd Allah , and he (the Imam) said, ‘The head is the place of slaughtering (intelligence), close to means for grazing and far from harms.’”
