It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that in the early days of Hajj, people used to buy and sell at Mina, Arafah, the market of Dhu al-Majaz and the other seasons of Hajj. Then they became afraid of trading while in the state of ihram, so Allah, the Mighty and Majestic, revealed this verse: "There is no blame upon you for seeking bounty from your Lord," meaning in the seasons of Hajj (trading is not a sin). Ubayd bin Umayr says that he used to read it this way (with the explanatory words) in his mushaf. 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 Nafi' and Salim that whenever Sayyiduna Ibn Umar (may Allah be pleased with them both) passed by Dhu al-Hulayfah, he would stay there for the night until morning came, and he used to report that this was also the practice of the Messenger of Allah (peace and blessings be upon him). This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it in this form.

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.

It is narrated from Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) was asked: Which deed is the most virtuous? He (peace and blessings be upon him) said: "Al-'ajj wa al-thajj (that is, calling out the talbiyah in a loud voice and shedding the blood of sacrificial animals)." The chain of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it. Abu Ubayd says: "Al-'ajj means raising the voice while calling out the talbiyah, and al-thajj means slaughtering the sacrificial camels so that blood flows from their throats."

It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whenever anyone calling out the talbiyah calls it out, every tree and stone on his right and on his left also calls out the talbiyah, until the earth, to its furthest extent on the right and on the left, resounds (with the same sound)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

Sa'id bin Jubayr (may Allah have mercy on him) relates: I said to Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both): O Abu al-Abbas, I am amazed at the disagreement of the Companions of the Messenger of Allah (peace and blessings be upon him) concerning the place where he (peace and blessings be upon him) entered into ihram. He said: "I am the most knowledgeable of people about this matter. In fact, the Messenger of Allah (peace and blessings be upon him) performed only one Hajj, and that is where the disagreement among the people arose. The Messenger of Allah (peace and blessings be upon him) set out for Hajj. When he (peace and blessings be upon him) had prayed two rak'ahs in the mosque at Dhu al-Hulayfah, he made ihram binding upon himself in that very sitting and called out the talbiyah as soon as he finished the prayer; some people heard it from him there and remembered it. Then he (peace and blessings be upon him) mounted, and when his she-camel rose up straight with him, he (peace and blessings be upon him) called out the talbiyah again, and some people heard it there. The reason for this was that people were coming in groups, one after another; they heard it when the she-camel rose up with him (peace and blessings be upon him), so they thought that he (peace and blessings be upon him) had entered ihram at that moment. Then the Messenger of Allah (peace and blessings be upon him) went on, and when he climbed the height of al-Bayda', he called out the talbiyah again, and some people heard it there and thought that he (peace and blessings be upon him) had entered ihram at that moment. Yet, by Allah, he (peace and blessings be upon him) had made ihram binding upon himself at his place of prayer, and then called out the talbiyah when the she-camel rose up straight, and also on the height of al-Bayda'." Sa'id bin Jubayr says: "So whoever adopts the view of Ibn Abbas (may Allah be pleased with them both) should enter ihram at his place of prayer as soon as he finishes the prayer." This hadith is sahih (authentic) on the condition of Imam Muslim and gives a detailed explanation on this topic, but the two Shaykhs (Bukhari and Muslim) did not record it.
