SHAFAQNA – Imam Sadeq (AS) said: Do not forget Ziarat Ashura and recommend to your friends to recite it because by doing so, your lifetime and sustenance will be increased; you will be granted a prosperous life and you will not die except that your name will be registered among the prosperous people by Allah (SWT) . In this regard, Imam Baqer (AS) also said: Imam Hussain (AS) was martyred whilst he was thirsty, calamities afflicted on him and aggrieved.
Therefore, Allah (SWT) did swear to the divine being that all those who have been afflicted with calamities, sinners, thirty, oppressed and aggrieved ones who face God near the holy grave of Imam Hussain (AS) whilst asking him to intercede on their behalf, will accept their prayers and grant their requests, forgive their sins, increase their lifetime and sustenance. So, take heed, O’ those with insight .
