6ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ حَكَمِ بْنِ أَيْمَنَ عَنْ قَاسِمٍ شَرِيكِ الْمُفَضَّلِ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) يَقُولُ الإسْلامُ يُحْقَنُ بِهِ الدَّمُ وَتُؤَدَّى بِهِ الأمَانَةُ وَتُسْتَحَلُّ بِهِ الْفُرُوجُ وَالثَّوَابُ عَلَى الإيمَانِ.
6. Ahmad ibn Muhammad has narrated from al-Husayn ibn Sa’id from Hakam ibn Ayman from Qasim associate of al-Mufaddal who has said that he heard Abu ‘Abdillah (a.s.) say the following: “Abu ‘Abd Allah (a.s.) has said, ‘Islam is to protect life, return the trust and make marriages lawful. Reward, however, comes from belief.’”
