Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 1
وَ فِي رِوَايَةِ أَبِي اَلْحُسَيْنِ اَلْأَسَدِيِّ رَضِيَ اَللَّهُ عَنْهُ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ جَعْفَرِ بْنِ عُثْمَانَ اَلدَّارِمِيِّ عَنْ سُلَيْمَانَ بْنِ جَعْفَرٍ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلتَّلْبِيَةِ وَ عِلَّتِهَا فَقَالَ «إِنَّ اَلنَّاسَ إِذَا أَحْرَمُوا نَادَاهُمُ اَللَّهُ عَزَّ وَ جَلَّ فَقَالَ «عِبَادِي وَ إِمَائِي لَأُحَرِّمَنَّكُمْ عَلَى اَلنَّارِ كَمَا أَحْرَمْتُمْ لِي» فَقَوْلُهُمْ لَبَّيْكَ اَللَّهُمَّ لَبَّيْكَ إِجَابَةٌ لِلَّهِ عَزَّ وَ جَلَّ عَلَى نِدَائِهِ لَهُمْ.
In a narration from Abu Al-Husayn Al-Asadi, may Allah سبحانه وتعالى be pleased with him, from Sahl bin Ziyad, from Ja'far bin Uthman Al-Darimi, from Sulayman bin Ja'far, he said: "I asked Abu Al-Hasan عليه السلام about the Talbiyah and its reason. Imam عليه السلام said: 'Indeed, when people enter Ihram, Allah سبحانه وتعالى, Mighty and Majestic, calls out to them, saying, "My servants and handmaids, I will make you forbidden upon the Fire just as you have entered Ihram for Me." Thus, their saying, 'Labbaik Allahumma Labbaik' (Here I am, O Allah سبحانه وتعالى, Here I am) is a response to Allah سبحانه وتعالى, Mighty and Majestic, for His call to them.'
