Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: I saw the Prophet (peace and blessings be upon him) gesturing like this with his blessed hand as he said: "Whoever separates from the community of the Muslims by a hand-span has removed the collar of Islam from his neck. And those who oppose with their banners will hold those banners on their backs on the Day of Resurrection." After this the narrator mentioned the full hadith, part of which is mentioned in the Sahih.
Al-Tabarani recorded it. Its chain contains Husayn bin Qays, who is da'if (weak).
