Is it true that if Imam Sajjad (AS) had been martyred in Karbala there would have been no Sayyid in the world today? Are all Sadaat in the world only from the progeny of Imam Hussain (AS)?
Allah (SWT) the Glorious, has saved Imam al-Sajjad (AS) in Kerbala to
keep the Imamate which is compulsory not only for Islam and Muslims
but also for the whole universe. Sadaat are not only the grand
children of Imam Husain (AS) but also the grand children of Imam Hasan
(AS) who are also called Hasani Sadaat. In fact all the Grand Children of Bani
Hashim, the grand-father of the Holy Prophet (SAWA) are called
Saadaat.
Wassalaam.
