وَ مَا رَوَاهُ سَعْدُ بْنُ عَبْدِ اَللَّهِ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِي هَمَّامٍ إِسْمَاعِيلَ بْنِ هَمَّامٍ قَالَ: رَأَيْتُ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ وَ كُنَّا عِنْدَهُ لَمْ يُصَلِّ اَلْمَغْرِبَ حَتَّى ظَهَرَتِ اَلنُّجُومُ ثُمَّ قَامَ فَصَلَّى بِنَا عَلَى بَابِ دَارِ اِبْنِ أَبِي مَحْمُودٍ
And that which was narrated by Sa’d ibn Abdillah from Ahmad ibn Muhammad, from Abu Hammam Isma’il ibn Hammam, who said:
I saw (Imam) al-Ridha عليه السلام, and we were with Him عليه السلام, and He عليه السلام did not pray Maghrib until the stars had appeared. Then He عليه السلام stood and led us in prayer at the door of the house of Ibn Abi Mahmud.
