Alqamah bin Mohammed ibn Hazrami (r.a.) narrates 'I requested Hazrat Imam Baqir (a.s.) to teach me a dua that I should recite on the day of Aashoora after the reciting the Ziyaarat of Imam Husain (a.s.) - from near his (a.s.) grave or from a distance.' Imam (a.s.) replied , 'O Alqamah, whenever you wish to recite the Ziyaarat of Imam Husain (a.s.), you first perform two units of prayers. Then turn towards the grave of Imam Husain (a.s.) and while pointing towards it, you first say 'Salam' and then 'Takbir'.

(a) Allah will increase your grade ten lakh times
(b) You will be included among those people who were martyred along with Imam Husain (a.s.)
(c) On the day of Judgment, you will be included among the martyrs
(d) You will get the reward of all the Prophets (a.s.) who have visited the grave of Imam Husain (a.s.) from the day that he (a.s.) was martyred till date. (Kaamil al-Ziyaarat, Ibn Qoolwayh, Ch. 71, p.194)
