It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that among the words of the talbiyah of the Messenger of Allah (peace and blessings be upon him) was also this: 'Labbayka ilaha al-haqq' (Here I am, O True God). This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) matted the hair of his head (before ihram) with ghisl (a cleansing substance such as marshmallow). This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it. However, both of them recorded the narration of Salim from Ibn Umar that the Prophet (peace and blessings be upon him) called out the talbiyah with his hair matted.

Khallad bin al-Sa'ib narrates from his father that the Prophet (peace and blessings be upon him) said: "Jibril came to me and said: Command your Companions to raise their voices in calling out the talbiyah."

It is narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Jibril (peace be upon him) came to me and said: O Muhammad, command your Companions to raise their voices while calling out the talbiyah, for it is the emblem of Hajj."

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Jibril (peace be upon him) commanded me to raise my voice while calling out the talbiyah, for it is one of the rites of Hajj." All of these chains are sahih (authentic), and none of them is a cause of defect ('illah) for another, because the righteous predecessors (Salaf) would have several chains gathered for a single text, just as they are gathered with us today; and the two Shaykhs (Bukhari and Muslim) did not record this hadith.
