It is narrated from Mus'ab bin Abdullah al-Zubayri that the name of the mother of Sayyiduna Abdullah bin Umm Maktum (may Allah be pleased with him) was Atikah bint Abdullah bin Ankathah bin Amir bin Makhzum, and he (himself) is Amr bin Qays bin Za'idah bin al-Asamm bin Harim bin Rawahah bin Abd bin Ma'is bin Amir bin Lu'ayy. The correct view is what Mus'ab said, because he affirmed both of his names.
