It is narrated from Sayyidah Duba'ah bint al-Zubayr bin Abd al-Muttalib (may Allah be pleased with her) that she slaughtered a sheep in her house, and the Messenger of Allah (peace and blessings be upon him) sent her a message: "Feed us too from your sheep." She said to the messenger: "Nothing is left of it except the neck, and I feel shy to send the neck to the Messenger of Allah (peace and blessings be upon him)." The messenger went back and informed the Messenger of Allah (peace and blessings be upon him), and the Messenger of Allah (peace and blessings be upon him) said: "Go back and tell her to send that very part, for it is the guide of the sheep (the foremost part), the nearest part of the sheep to good and the farthest from harm."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from Sayyidah Duba'ah bint al-Zubayr (may Allah be pleased with her) except with this chain; Usamah bin Zayd is alone in narrating it."
