Yes, he (SAAW) did not have a son but his lineage continued through his Daughter Bib Fatima (AS) not Daughters. He had only one child from him that grew up and had kids. The other two daughters were nieces of Hazrat Khadia (AS) and were raised by the Prophet (SAAW) and his favorite wife (AS).
Please quote me where it says the covenant ended with the prophet (SAAW)?
The Muhammad (saw) had four REAL daughter. They were as much his ‘flesh and blood’ as Hz. Hassan and Hussein (May Allah (swt) be pleased with them both) were ‘flesh and blood’ of Hz. Ali (ra).
They were the REAL of the Prophet (saw) from Hz. Khadijah (ra).
Their names are as follows:
Hz. Zainab bint Muhammad, Hz. Ruqayah bint Muhammad and Hz. Umm Kulthum bint Muhammad Hz. Fatimah bint Muhammad (May Allah (swt) be pleased with them all).
They are always addressed as “bint Muhammad” – (daughter of Muhammad) (even by Shia scholars!!!!!) .
Recall Hz. Zaid bin Harith (ra) was once called Zaid bin Muhammad as the Prophet (saw) had adopted him. By the direct command Allah (swt) in the Quran Hz. Zaid (ra) was called by his proper name using his real father’s name. Hence on he was always called as Zaid bin Harith.
In Islam a child MUST carry the father’s name if it is known.
Had these noble souls been daughters of ‘someone’ else’ then they wouldn’t have been addressed as ‘Bint Muhammad.
Shias deny this just to give exclusivity to Hz. Fatimah (ra) and of course exclusivity to Hz. Ali (ra) for being the only son in law of the Prophet (saw)!!!
Trust me the Prophet (saw) had other REAL son in laws and cousins too!!!
This is an open insult to Prophet (saw) by attributing fatherhood of his own flesh and blood to some other unknowns!
The above has nothing to do with Hz. Ali (ra)'s divine right to the Leadership!
