Ruqaiyyah Waris Maqsood. «The Prophet's Family Line No 5 Abdul Muttalib»(en inglés). Archivado desde el original el 1 de diciembre de 2017. Consultado el 11 de agosto de 2018. «Abdu’l Muttalib matured into a deeply religious man, but in spite of the honour of his position as Guardian of the Ka’bah, he found his personal sympathies lay with the hanifs and not with the multitudes of pagan worshippers who streamed in pilgrimage to the shrine. He used to go off alone to spend long hours of prayer out on the hillsides around Makkah, as his friend Zayd b. Amr the hanif had done.»
