The Mother of the Believers, Sayyidah Umm Salamah (may Allah be pleased with her), narrates: "The Messenger of Allah (peace and blessings be upon him) granted Sayyidah Sahlah bint Suhayl (may Allah be pleased with her) a special concession in the matter of suckling (rada'ah)," and the Mother of the Believers, Sayyidah Umm Salamah (may Allah be pleased with her), did not herself act upon it.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Mus'ab bin Abdullah except al-Zubayr, and no one from al-Zubayr except Abd al-Aziz, and Abdullah bin Marwan is alone in narrating it."
