It is narrated from Shabab that Muhammad bin Abdullah bin Jahsh bin Ri'ab bin Ya'mar bin Sabirah bin Kabir bin Ghanm bin Dudan bin Asad bin Khuzaymah (this is his lineage) was an ally of Banu Umayyah; his paternal grandmother, Umaymah bint Abd al-Muttalib, was the paternal aunt of the Messenger of Allah (peace and blessings be upon him), and his paternal aunt, Sayyidah Zaynab bint Jahsh (may Allah be pleased with her), was the pure wife of the Prophet (peace and blessings be upon him).
