Musannaf Ibn Abi Shaybah 25889 — Atirah and fara'ah

Amr bin Shu'ayb reports from his father, from his grandfather, that the Messenger of Allah (peace and blessings be upon him) was asked about fara'. He (peace and blessings be upon him) said: "Fara' is valid. But that you leave it until this young animal grows big, two or three years old, and then carry loads on it in the path of Allah, or give it to a widow, is better than that you slaughter it, so that its flesh mixes with its hair, and you overturn your pot and drive your she-camel mad." And the questioner asked him (peace and blessings be upon him) about the atirah, and he (peace and blessings be upon him) remained silent. A man asked Sayyiduna Umar (may Allah be pleased with him) about it, and he said: "We used to call it the Rajabiyyah. A household would slaughter a goat in the month of Rajab and eat it."
