6ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ وَغَيْرِهِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ لا يُنْشَدُ الشِّعْرُ بِلَيْلٍ وَلا يُنْشَدُ فِي شَهْرِ رَمَضَانَ بِلَيْلٍ وَلا نَهَارٍ فَقَالَ لَهُ إِسْمَاعِيلُ يَا أَبَتَاهْ فَإِنَّهُ فِينَا قَالَ وَإِنْ كَانَ فِينَا.

6. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Hammad ibn ‘Uthman and others who has said the following: “Abu ‘ Abd Allah, ‘Alayhi al-Salam, has said, ‘You must not read poems during the night. You must not read poems in the month of Ramadan during the night or during the day.’ Isma‘il then said, ‘Father, but it is in our praise.’ The Imam said, ‘Even if it is in our praise, do not read poems.’”
