It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said these words in his talbiyah «‏‏‏‏لَبَّيْكَ إِلٰهَ الْحَقِّ» ‏‏‏‏: "O True and Real Deity, I am present in Your court."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that these words were also included in the Talbiyah of the Messenger of Allah (peace and blessings be upon him) «‏‏‏‏لَبَّيْكَ إِلٰهَ الْحَقِّ» ‏‏‏‏ "O God of Truth, I am present in Your service."

Hazrat Khallad bin Sa’ib narrates from his esteemed father, Sayyiduna Sa’ib (may Allah be pleased with him), that the Noble Prophet (peace and blessings be upon him) said:“Jibreel (peace be upon him) came to me and said, ‘Command your companions to raise their voices while reciting the Talbiyah.’”In the narration of Ahmad, the words are“with Ihlaal and Talbiyah.”(Both mean to call out the Talbiyah.)

Hazrat Ja'far narrates from his respected father, who says that we presented ourselves before Sayyiduna Jabir bin Abdullah (may Allah be pleased with him), and we asked him about the Hajj of the Messenger of Allah (peace and blessings be upon him). So he said that the Prophet set out for the journey of Hajj until his mount took him to the place of Bida’, then the Messenger of Allah (peace and blessings be upon him) raised his voice and proclaimed these words of Tawheed «‏‏‏‏لَبَّيْكَ اللَٰهُمَّ لَبَّيْكَ، لَبَّيْكَ لاَ شَرِيكَ لَكَ لَبَّيْكَ، إِنَّ الحَمْدَ وَالنِّعْمَةَ لَكَ وَالمُلْكَ، لاَ شَرِيكَ لَكَ» ‏‏‏‏:“O Allah, I am present in Your court, I am steadfast in Your worship. I am present in Your court for Your obedience. You have no partner. O Allah, I am present in Your service. Surely, all praise and glory are worthy only of You. All blessings are in Your control. Sovereignty is Yours. You have no partner.”While the noble Companions would add the words“Dhul-Ma‘arij”(O Possessor of the stairs), and the Noble Prophet (peace and blessings be upon him), even after hearing these words, would not say anything to them.

Sayyiduna Sa’ib رضي الله عنه narrates from the Noble Prophet صلى الله عليه وسلم that he said:“Jibreel عليه السلام came to me and said: ‘Order your companions to proclaim the Talbiyah in a loud voice.’”In the narration of Janab Ahmad bin Mani’, the words are:“with raising the voice and with the Talbiyah.”

The person reciting the Talbiyah has been commanded to proclaim the Talbiyah aloud for this very reason, because it is a symbol of Hajj.

It is narrated from Sayyiduna Zaid bin Khalid Al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: "Jibreel (peace be upon him) came and said: 'O Muhammad (peace be upon him), command your companions to recite the Talbiyah aloud, for this is the symbol of Hajj.'"

Sayyiduna Zaid bin Khalid Juhani رضي الله عنه narrates that the Messenger of Allah صلى الله عليه وسلم said:“Jibreel عليه السلام came to me and said, ‘Make Talbiyah your slogan because Talbiyah is the slogan of Hajj.’”Imam Abu Bakr رحمه الله says that these words,“Talbiyah is the slogan of Hajj,”belong to the same category about which I have already explained that the Arabs say,“This is the best deed,”and by this they mean that this deed is among the best of deeds. Sometimes the Arabs say,“The best deed is such and such,”and by this they mean that this deed is one of the better deeds among the best deeds. Similarly, the statement of the Noble Prophet صلى الله عليه وسلم:“Talbiyah is the slogan of Hajj,”means that Talbiyah is one of the slogans of Hajj.

Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace be upon him) said: "Jibreel (peace be upon him) ordered me to recite the Talbiyah aloud because it is one of the symbols of Hajj." Imam Abu Bakr (may Allah have mercy on him) says that I have mentioned the chains of this hadith in Kitab al-Kabir.
