4ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ آخِرُ الْعَقِيقِ بَرِيدُ أَوْطَاسٍ وَقَالَ بَرِيدُ الْبَعْثِ دُونَ غَمْرَةَ بِبَرِيدَيْنِ.
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following: “One of the two Imam, (abu Ja’far or abu ‘Abd Allah), ‘Alayhim al-Salam, has said, ‘The last section of al-‘Aqiq is Barid of Awtas.’ He (the Imam) said, ‘Barid al-Ba‘th is two Barid before Ghamrah.””
