All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
The Prophet had seven children, three sons and four daughters. Their names are as follows:
1) Al-Qaasim: The Prophet was nicknamed by the name of this son. The nickname of the Prophet, sallallaahu ‘alayhi wa sallam, was Abul-Qaasim.
2) ‘Abdullaah, also called At-Taahir and At-Tayyib. The mother of both sons was Khadeejah bint Khuwaylid .
3) Ibraaheem, the last child of the Prophet : his mother was Maariyah Al-Qibtiyyah. All the sons of the Prophet, sallallaahu ‘alayhi wa sallam, died in childhood.
4) Zainab, 5) Ruqayyah, 6) Umm Kulthoom, and 7) Faatimah .
Faatimah was the daughter loved most by the Prophet, sallallaahu ‘alayhi wa sallam. All the children of the Prophet, sallallaahu ‘alayhi wa sallam, were born from Khadeejah except for Ibraaheem, who was from Maariyah Al-Qibtiyyah. He did not have any children from his other wives all.
Allaah Knows best.
