Another responsibility is to supplicate for the victory of the Imam over the disbelievers, hypocrites, those who do not accept him and all of his adversaries. In summary, this supplication should be targeted against all enemies of the religion of Allah.
One of the best supplications to use in these regards is Du’a al-Nudbah1, however there are many other ones mentioned in the books of supplication.
In Du’a al-Nudbah, we come across many lines which convey the victory of the Imam:
أَللّٰهُمَّ وَ أَقِمْ بِهِ الْـحَقَّ وَ أَدْحِضْ بِهِ الْبَاطِلَ...
“O’ Allah! Through him (the Imam), establish truth and destroy all falsehood.”
In addition, we read:
وَ أَذْلِلِ بِهِ أَعْدَائَكَ...
“Through him (the Imam), humiliate all of your enemies.”
