Sahih al-Bukhari Book 47, Hadith 21
The Prophet (along with his companions) reached Mecca in the morning of the fourth of Dhul-Hijja
assuming Ihram for Hajj only. So when we arrived at Mecca, the Prophet (ﷺ) ordered us to change our
intentions of the Ihram for `Umra and that we could finish our Ihram after performing the `Umra and
could go to our wives (for sexual intercourse). The people began talking about that. Jabir said
surprisingly, "Shall we go to Mina while semen is dribbling from our male organs?" Jabir moved his
hand while saying so. When this news reached the Prophet (ﷺ) he delivered a sermon and said, "I have
been informed that some peoples were saying so and so; By Allah I fear Allah more than you do, and
am more obedient to Him than you. If I had known what I know now, I would not have brought the
Hadi (sacrifice) with me and had the Hadi not been with me, I would have finished the Ihram." At that
Suraqa bin Malik stood up and asked "O Allah's Messenger (ﷺ)! Is this permission for us only or is it
forever?" The Prophet (ﷺ) replied, "It is forever." In the meantime `Ali bin Abu Talib came from Yemen
and was saying Labbaik for what the Prophet (ﷺ) has intended. (According to another man, `Ali was
saying Labbaik for Hajj similar to Allah's Messenger (ﷺ)'s). The Prophet (ﷺ) told him to keep on the Ihram and
let him share the Hadi with him.
The Prophet (ﷺ) said, "Whoever manumits his share of a jointly possessed slave, it is essential for him to manumit the slave completely if he has sufficient money. Otherwise he should look for some work for the slave (to earn what would enable him to emancipate himself), without overburdening him with work."
My grandfather, Rafi` bin Khadij said, "We were in the valley of Dhul-Hulaifa of Tuhama in the company of the Prophet (ﷺ) and had some camels and sheep (of the booty). The people hurried (in slaughtering the animals) and put their meat in the pots and started cooking. Allah's Messenger (ﷺ) came and ordered them to upset the pots, and distributed the booty considering one camel as equal to ten sheep. One of the camels fled and the people had only a few horses, so they got worried. (The camel was chased and) a man slopped the camel by throwing an arrow at it. Allah's Messenger (ﷺ) said, 'Some of these animals are untamed like wild animals, so if anyone of them went out of your control, then you should treat it as you have done now.' " My grandfather said, "O Allah's Messenger (ﷺ)! We fear that we may meet our enemy tomorrow and we have no knives, could we slaughter the animals with reeds?" The Prophet (ﷺ) said, "Yes, or you can use what would make blood flow (slaughter) and you can eat what is slaughtered and the Name of Allah is mentioned at the time of slaughtering. But don't use teeth or fingernails (in slaughtering). I will tell you why, as for teeth, they are bones, and fingernails are used by Ethiopians for slaughtering. (See Hadith 668)
