1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ قَالَ
سَأَلْتُهُ لِمَ جُعِلَتِ التَّلْبِيَةُ فَقَالَ إِنَّ الله عَزَّ وَجَلَّ أَوْحَى إِلَى إِبْرَاهِيمَ (عَلَيْهِ السَّلاَم) أَنْ أَذِّنْ فِي النَّاسِ بِالْحَجِّ يَأْتُوكَ رِجالاً وَعَلى كُلِّ ضامِرٍ يَأْتِينَ مِنْ كُلِّ فَجٍّ عَمِيقٍ فَنَادَى فَأُجِيبَ مِنْ كُلِّ وَجْهٍ يُلَبُّونَ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following:
“I once asked him (the Imam) 
, about why Talbiyah is required. He (the Imam) said, ‘Allah, most Majestic, most Glorious, sent revelation to Ibrahim ‘Alayhi al-Salam that said, ‘Call people for al-Hajj. They will come to you on foot and on lean camels from all directions.’ He called and his call was answered from all directions with al-Talbiyah (here I am O Lord, to obey Your command).”’
