٩ـ عَنْهُ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ حَمَّادٍ عَنْ حَرِيزٍ عَنْ رَجُلٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) قَالَ قُلْتُ لَهُ فَصَلِّ لِرَبِّكَ وَانْحَرْ قَالَ النَّحْرُ الاعْتِدَالُ فِي الْقِيَامِ أَنْ يُقِيمَ صُلْبَهُ وَ نَحْرَهُ وَقَالَ لاَ تُكَفِّرْ فَإِنَّمَا يَصْنَعُ ذَلِكَ الْمَجُوسُ وَلاَ تَلَثَّمْ وَلاَ تَحْتَفِزْ وَلاَ تُقْعِ عَلَى قَدَمَيْكَ وَلاَ تَفْتَرِشْ ذِرَاعَيْكَ. 
9. It is a narration from him (narrator of previous Hadith) by Ahmad ibn Muhammad from Hammad from Hariz from a man who has said the following: “I once asked abu Ja‘far , about the words of Allah, ‘Perform Salah (prayer) for the sake of your Lord and offer sacrifice. . . .’(108:2) He (the Imam) said, ‘Offering sacrifice’ is a reference to standing in a level posture by keeping one’s back and neck level.’ He (the Imam) said, ‘You must not place your hand on your other hand; Majus (Zoroastrians) people would do so. You must not cover your mouth, do not hold your limbs tightly together and do not squat (sit on one’s heels) and do not place your arms flat on the ground.’” (Ahadith 7-9 above and the following chapters are best explained in the form of fatwa).
