Mujahid (may Allah have mercy on him) said: The Prophet (peace and blessings be upon him) disliked seven things of a slaughtered goat: "the blood, the gall bladder, the male organ, the testicles, the female organ, the glands and the bladder." And the front part of the goat (that is, its meat) was what he liked.
This is munqati' (its chain is broken).

Mujahid narrates from Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) "disliked seven things of the goat," and in this way he mentioned the hadith.
Abu Sulayman al-Khattabi (may Allah have mercy on him) said: Blood is unlawful by consensus, but the other things are disliked (makruh).
Umar bin Musa bin Wajih, who narrated it as connected, is da'if (weak), and its being connected is not sound.
