Chapter on Virtues of Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ قَالَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ: «مَا مِنْ مُهِلٍّ يُهِلُّ فِي اَلتَّلْبِيَةِ إِلاَّ أَهَلَّ مَنْ عَنْ يَمِينِهِ مِنْ شَيْءٍ إِلَى مَقْطَعِ اَلتُّرَابِ وَ مَنْ عَنْ يَسَارِهِ إِلَى مَقْطَعِ اَلتُّرَابِ وَ قَالَ لَهُ اَلْمَلَكَانِ أَبْشِرْ يَا عَبْدَ اَللَّهِ وَ مَا يُبَشِّرُ اَللَّهُ عَبْداً إِلاَّ بِالْجَنَّةِ ».
Commander of the Faithful Imam Ali ibn Abi Talib عليه السلام said: "There is no one who raises their voice in Talbiyah (Labbaik Allahumma Labbaik) except that everything to their right up to the ends of the earth and everything to their left up to the ends of the earth also proclaims the Talbiyah. Then the two angels say to them: 'Rejoice, O servant of Allah سبحانه وتعالى!' And Allah سبحانه وتعالى does not give glad tidings to a servant except with Paradise."
