Imam Sadiq (a.s) narrates that “one who recites this supplication for 40 mornings; he will be accounted amongst the helpers of Imam Mahdi (a.t.f.s). And if he happens to die before the reappearance of Imam Mahdi (a.t.f.s), Allah will raise him up from his grave so that he may assist the holy Imam (a.t.f.s).
For every word that he recites in this supplication, Allah will grant him 1000 good deeds and will erase from his scroll of deeds 1000 sins”. As the title suggests, this supplication is of allegiance (ahad) to the holy Imam (a.t.f.s). Its recitation every morning ensures the renewal of this covenant as taught by Imam Ali ibne Abi Talib (as)
(We pray for Your) earliest advent, earliest advent, O Patron of the Age.
THE SECOND SUPPLICATION OF AL-AHD
From the authority of Jabir bn Yazid AL-Ja'afi, Abu Ja'afar (peace be on him) said: whoever offer this supplication once in his life time, he will be written among those that are free from slavery and will be written in the register of the Imam (peace be on him), and will be called with his name and that of his father when Imam Al-Mahdi rise up, then the book will be given to him and it shall be said to him, take the covenant book for your covenant with us in the world; that is the saying of Allah which says:
« إِلّا مَنِ اتَّخَذَ عِنْدَ الرَّحْمنِ عَهْداً »
{save those who have taken with the All-mercy covenant}[1]
Then offer the following supplication while in a state of purification:
أَللَّهُمَّ يا إِلهَ الْآلِهَةِ ، يا واحِدُ ، يا أَحَدُ ،
يا آخِرَ الْآخِرينَ ، يا قاهِرَ الْقاهِرينَ ، يا عَلِيُّ يا عَظيمُ ،
