Abdullah Ibn Umm Maktum (RA) also known as Amru Ibn Umm Maktoom was a companion of the Prophet Muhammad (SAW). He was blind from birth, so his mother Aatika was nicknamed 'Umm Maktum' - the mother of the blind.
Abdullah Ibn Umm Maktum (RA) was the first cousin of the Prophet's wife Khadija (RA). He was among the first converts to Islam. He suffered along with his brothers when the Muslims were persecuted in Makkah.
