Imam Hasan al Mujtaba

Whenever Imam Hasan (A.S) became depressed, he would sit in a room and recite this prayer:
یا كهيعص يَا نُورُ يَا قُدُّوس يَا خَبيرُ يَا اللهُ يَا رَحْمَانُ
O Kaf Ha Ya Aayn Saad, O Light, O the Most Holy One, O the Aware, O Allah, O the Beneficent.
[This phrase should be repeated 3 times]
اغْفِرْ لِيَ الذُّنُوبَ الَّتي تُحِلُّ النِّقَمَ وَاغْفِرْ لِيَ الذُّنُوبُ الَّتي تُغَيِّر النِّعَمَ وَاغْفِرْلِيَ الذُّنُوبَ الَّتي تَهْتِكُ الْعِصَمْ وَاغْفِرْ لِيَ الذُّنُوبُ الَّتي تُنْزِلُ الْبَلاَءَ وَاغْفِرْ لِيَ الذُّنُوبَ الَّتي تُعَجِّلُ الْفَنَاءَ وَاغْفِرْ لِيَ الذُّنُوبَ الَّتي تُدِيلُ الاَْعْدَاءَ وَاغْفِرْ لِيَ الذُّنُوبَ الَّتي تَقْطَعُ الرَّجَاءَ وَاغْفِرْ لِيَ الذُّنُوبَ الَّتي تَرُدُّ الدُّعَاءَ وَاغْفِرْ لِيَ الذُّنُوبَ الَّتي تُمْسِكُ غَيْثَ السَّمَاء وَاغْفِرْ لِيَ الذُّنُوبَ الَّتي تُظْلِمُ الْهَوَاءَ وَاغْفِرْ لِيَ الذُّنُوبَ الَّتي تَكْشِفُ الْغِطَاءَ.

Forgive all my sins that bring misery, and forgive the sins that convert blessings to vengeance, and forgive my sins that destroy the innocence, and forgive the sins that bring down the disasters, and forgive the sins which hasten death and destruction, and forgive the sins which make the enemies dominate us, and forgive the sins which discourage all the hopes, and forgive the sins which make the prayers be rejected, and forgive the sins which hinder the descent of the rain, and forgive the sins which darken the air, and forgive the sins which removes the covers of sins.
Then, he asked for his requests.
