Bayhaqi 10076 — Collected chapters on being prevented (ihsar)

Sayyiduna al-Miswar bin Makhramah (may Allah be pleased with him) and Marwan bin al-Hakam (may Allah have mercy on him), each of whose narrations confirms the other's, both said: The Messenger of Allah (peace and blessings be upon him) set out in the year of al-Hudaybiyah with more than a thousand of his Companions. When he (peace and blessings be upon him) came to Dhu al-Hulayfah, he garlanded his sacrificial animals there and marked them (ish'ar: slitting the camel's hump on the right side so that it is known as a sacrificial animal), and entered ihram for Umrah. (The narrator) mentioned his (peace and blessings be upon him) camping at the far edge of al-Hudaybiyah, then the coming of Suhayl bin Amr, and the terms that were settled with him when they prevented him from the House. When he (peace and blessings be upon him) had finished with the treaty, he said to his Companions: "Get up, slaughter your sacrifices, then shave your heads." The narrator said: By Allah, not a single one of them got up, until he (peace and blessings be upon him) had said it three times. When none of them got up, he went in to Umm Salamah (may Allah be pleased with her) and mentioned to her what he had met with from the people. Umm Salamah (may Allah be pleased with her) said: O Messenger of Allah (peace and blessings be upon him), would you like that (they do it)? Go out, then do not speak a word to any of them until you have slaughtered your sacrificial camels and called your barber to shave your head. So he (peace and blessings be upon him) got up and went out, and did not speak to any of them until he had done that: he slaughtered his sacrifice and called his barber, who shaved his head. When the people saw that, they got up and slaughtered their sacrifices, and began shaving one another's heads, until they almost killed one another out of grief.
