7ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ جَعْفَرِ بْنِ سَمَاعَةَ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبَانٍ عَنْ زُرَارَةَ بْنِ أَعْيَنَ قَالَ سَأَلْتُ أَبَا جَعْفَرٍ (عَلَيْهِ السَّلام) مَا حَقُّ الله عَلَى الْعِبَادِ قَالَ أَنْ يَقُولُوا مَا يَعْلَمُونَ وَيَقِفُوا عِنْدَ مَا لا يَعْلَمُونَ.
7. Al-Husayn ibn Muhammad has narrated from Mu‘alla ibn Muhammad from Ali ibn Asbat from Ja’far ibn Sama‘a from several persons, from aban, from Zurara ibn A‘yan who has said the following. “I asked Imam abu Ja‘far عليه السلام this, ‘What are the rights of Allah on people?’” The Imam عليه السلام replied, “They must say what they know and abstain from saying anything that they have no knowledge of.’”
