3ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَبْدِ الْمَلِكِ بْنِ عُتْبَةَ الْهَاشِمِيِّ قَالَ سَأَلْتُ أَبَا الْحَسَنِ يَعْنِي مُوسَى (عَلَيْهِ السَّلاَم) عَنِ الرَّجُلِ يُجَامِعُ أَهْلَهُ فِي السَّفَرِ وَهُوَ فِي ��َهْرِ رَمَضَانَ قَالَ لا بَأْسَ بِهِ.
3. Ahmad ibn Muhammad has narrated from Ali ibn al-Hakam from ‘Abd al-Malik ibn ‘Utbah al-Hashimiy who has said the following: “I once asked abu al-Hassan, Musa , about a man who experiences sexual relation with his wife during a journey in the month of Ramadan. He (the Imam) said, ‘It is not harmful.’”
