2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ كَبَّرَ أَمِيرُ الْمُؤْمِنِينَ (صلّى اللهُ عَلَيْهِ وَآلِه) عَلَى سَهْلِ بْنِ حُنَيْفٍ وَكَانَ بَدْرِيّاً خَمْسَ تَكْبِيرَاتٍ ثُمَّ مَشَى سَاعَةً ثُمَّ وَضَعَهُ وَكَبَّرَ عَلَيْهِ خَمْسَةً أُخْرَى فَصَنَعَ ذَلِكَ حَتَّى كَبَّرَ عَلَيْهِ خَمْساً وَعِشْرِينَ تَكْبِيرَةً.
2. Ali ibn Ibrahim has narrated from his father from ibn Abu ‘Umayr from Hammad from al-Halabi who has said the following: “Abu ‘Abd Allah (a.s.) has said, ‘’Amir al-Mu’minin (a.s.) said five takbirs over Sahl ibn Hunayf who was a Badri, (participant in the battle of Badr). He (Imam 'Ali) then walked for a while, then placed him on the ground and said another five Takbir and so on until he had said twenty five Takbir.’”
