It is narrated from Mohammad ibn Moslem who said: I heard from Imam Baqer (AS) and Imam Sadeq (AS) who said: Allah (SWT) has granted three special things to Imam Hussain (AS) instead of his martyrdom.

1. Granted Imamate to his children, and all infallible Imams after him are from his children.
2. Granted cure in soil of his blessed grave.
3. Granted acceptance of Dua near his holy grave; and the days which pilgrims visit his grave are not counted as their lifetime 1.

It is also narrated from the Prophet of Islam (PBUH) who said: The martyrdom of Imam Husaain (AS) has established such fire, heat, love and burning in the hearts of the believers which will never get cold or extinguished 2.
