Duaas and Azkaar after Salaah

After completing one’s fardh salaah, one should place one’s right hand on his forehead and thereafter pass it over his head and recite the following duaa:

بِسْمِ اللَّهِ الَّذِي لَا إِلَهَ إِلَّا هُوَ الرَّحْمَنُ الرَّحِيمُ، اللَّهُمَّ أَذْهِبْ عَنِّي الْهَمَّ وَالْحَزَنَ

In the name of Allah, the One besides whom there is no other deity, the Beneficent, the Merciful.…

One should recite the following duaa after salaah:

اللَّهُمَّ اغْفِرْ لِي مَا قَدَّمْتُ وَمَا أَخَّرْتُ، وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ، وَمَا أَسْرَفْتُ وَمَا أَنْتَ أَعْلَمُ بِهِ مِنِّي، أَنْتَ الْمُقَدِّمُ وَأَنْتَ الْمُؤَخِّرُ، لَا إِلَهَ إِلَّا أَنْتَ

O Allah, forgive my sins, my past sins and my future sins, the sins done in secret and the sins committed openly, and the (major) sins where I surpassed the limits (of Shariah) and those sins that You know more than me.…
