Another responsibility is to ask Allah to remove His mercy from the enemies of the Imam, as this is one of the best ways to show our hatred for his enemies.
A true believer must keep these enemies in mind, ask Allah to remove His specific mercy from them, and pray to Allah to increase His chastisement over them. This act is actually considered as a good deed and in addition, it has a positive effect on the spirit of a person and will assist in strengthening his soul against the opposing enemies!
The greatest historical enemies of Imam al-Mahdi (ajtf) include the Bani Umayyah and Bani ‘Abbas and the believer must remember to curse these people every day and night with his heart and tongue.
The simplest level of ‘cursing’ them is to detest them through one’s actions. In this regards, Imam Muhammad b. ‘Ali al-Baqir (as) has said:
إِذَا انْحَرَفْتَ عَنْ صَلاَةٍ مَكْتُوْبَةٍ فَلاَ تَنْحَرِفْ إِلاَّ بِانْصِرَافِ لَعْنِ بَنِي أُمَيَّةَ
“When you have departed from your obligatory Salat then do not leave (your prayer area) until you have cursed the Bani Umayyah.”1
The Messenger of Allah has said:
مَنْ ضَعُفَ عَنْ نُصْرَتِنَا أَهْلَ الْبَيْتِ فَلَعَنَ فِي خَلَوَاتِهِ أَعْدَائَنَا بَلَّغَ اللٌّهُ صَوْتَهُ جَمِيعَ الأَمْلاَكِ مِنَ الثَّرى إِلــى الْعَرْشِ فَكُلَّمَا لَعَنَ هٌذَا الرَّجُلُ أَعْدَائَنَا لَعْناً سَاعَدُوهُ فَلَعَنُوا مَنْ يَلْعَنُهُ ثُمَّ ثَنَّوْهُ فَقَالُوا: أَللٌّهُمَّ صَلِّ عَلـى عَبْدِكَ هٌذَا الَّذِي قَدْ بَذَلَ مَا فِي وُسْعِهِ وَ لَوْ قَدَرَ عَلـى أَكْثَرَ مِنْهُ لَفَعَلَ. فَإِذَا النِّدَاءُ مِنْ قِبَلِ اللٌّهِ تَعَالـى: قَدْ أَجَبْتُ دُعَاءَكَمْ وَ سَمِعْتُ نِدَاءَكُمْ وَ صَلَّيْتُ عَلـى رُوْحِهِ فِي الأَرْوَاحِ وَ جَعَلْتُهُ عِنْدِي مِنَ الْمُصْطَفَينَ الأَخْـيَارِ
“If one is too weak to support us the Ahlul Bayt (in open) and thus curses our enemies in secret, Almighty Allah makes his voice reach all the creatures from the earth up to the Divine Throne (‘Arsh).
Hence, whenever one curses our enemies, they support him by cursing the one whom he is cursing then they laud him saying: “O Allah! (Please) send blessings on this servant of yours who is doing the best he can and who would certainly do more if he could.”
Almighty Allah answers: “I have responded to your prayers and have listened to your requests therefore, I send blessings upon the soul of this servant and I include him with the ‘Company of the Elect, the Virtuous.’”2
