Musannaf Ibn Abi Shaybah 35209 — What they said on sealing the necks

Maymun bin Mihran (may Allah have mercy on him) said that Sayyiduna Umar (may Allah be pleased with him) sent Sayyiduna Hudhayfah bin al-Yaman (may Allah be pleased with him) and Sayyiduna Ibn Hunayf (may Allah be pleased with him), and the two of them assessed the jizyah upon the people of al-Sawad. They both said: "Whoever among the people of al-Sawad does not come and have his neck sealed, the covenant of protection is withdrawn from him."
