SHAFAQNA – Mohammad ibn Moslem narrated: I heard from Imam Baqer (AS) and Imam Sadeq (AS) who said: Allah (SWT) granted Imam Hussain (AS) three special attributes for his martyrdom.
1. Imamate has been bestowed on his progeny, and all infallible Imams (AS) after Imam Hussain (AS) are children of Imam Hussain (AS).
2. God granted cure and wellness to his torbah (Torbat).
3. Dua is accepted by God near the grave of Imam Hussain (AS), and the days his pilgrims visiting his holy shrine, are not counted as their lifetime .
