How sound is the hadith narrated by Lady Aminah concerning her seeing a light when she became pregnant with the Prophet, peace and blessings be upon him, and successive visits from prophets each month of her pregnancy, giving her glad tidings of him, as mentioned in the book "Nuzhat al-Majalis"?

This report does not have an isnad (chain of narration). However, its first paragraph is mentioned in "Al-Musnad" by Imam Ahmad, on the authority of Al-ʿIrbad ibn Sariyah Al-Sulami, who said: I heard the Messenger of Allah, peace and blessings be upon him, say: "Indeed, I am with Allah in the Mother of the Book, the Seal of the Prophets, even while Adam was still intertwined with his clay. And I shall inform you of the interpretation of that: it is the supplication of my father Abraham, the glad tidings of Jesus to his people, and the vision of my mother, who saw a light emanating from her that illuminated the palaces of Syria, and similarly do the mothers of the Prophets, peace be upon them, see."

The verifiers of Al-Musnad said: "It is sahih li ghayrihi (authentic due to external corroboration) except for the phrase: 'and similarly do the mothers of the Prophets, peace be upon them, see.'" Al-Albani said: "The hadith is authentic without the last addition: 'and similarly do...' So, refer to the hadith: 'I am the supplication of Abraham...' (1546 and 1925) from 'Al-Silsilah Al-Sahihah'."
