Ibn Abbas (Allah be pleased with them) reported that Allah's Messenger (ﷺ) sent eighteen sacrificial camels with a person. The rest of the hadith is the same, and the first part (of the above-mentioned hadith) is not mentioned.
Sahih Muslim Book 15, Hadith 421
← Previous Hadith I and Sinan b. Salama proceeded (to Mecca to perform Umra. Sinan had a sacrificial camel with him which he was driving. The camel stopped in the way being completely exhausted and this state of it made him (Sinan) helpless. (He thought) if it stops proceeding further how he would be able to take it, along with him and said: I would definitely find out (the religious verdict) about it. I moved on in the morning and as we encamped at al-Batha', (Sinan) said: Come (along with me) to Ibn 'Abbis (Allah be pleased with them) so that we should narrate to him (this incident), and he (Sinan) reported to him the incident of the sacrificial camel. He (Ibn Abbas) said: You have referred (the matter) to the well informed person. (Now listen) Allah's Messenger (ﷺ) sent sixteen sacrificial camels with a man whom he put in change of them. He set out and came back and said: Messenger of Allah, what should I do with those who are completely exhausted and become powerless to move on, whereupon he said: Slaughter them, and dye their hoofs in their blood, and put them on the sides of their humps, but neither you nor anyone among those who are with you must eat any part of them.

Sahih Muslim Book 15, Hadith 420 Next Hadith → If any of these is completely exhausted and you apprehend its death, then slaughter it, then dip its hoofs in its blood and imprint it on its hump; but neither you nor any one of your comrades should eat it.
