The Islamic manner of having one’s sins Forgiven
Anyone who recites after each Salah Istighfaar three times, Ayat-ul-Kursi, the three Quls once, ‘SubhanAllah’ thirty three times, ‘Alhumdillah’ thirty three times, and Allahu Akbar thirty four times and the following once, then Allah will forgive all his sins, even if they are more than the foam of the ocean.
La ilaha illAllahu Wahdahu la Shareeka Lahu lahul Mulku wa Lahul Hamdu wa Huwa ‘Ala Kulli Shay’in Qader
“There is no God but Allah, He is the one and He has no partner. For Him is the Kingdom and Praise and He has the power over all things possible.”
Supplication: After every Salaah, A person should place their right hand on the forehead, drawing it towards the back of the head and recite the Following:
Bismillahil-ladhi la llaha illa Huwar-Rahmanur Raheem Allahumma
Adhhid ‘Annil Hamma wal Huzana
“Allah In The Name Of, Who Is The Only One Worthy Of Worship, The Most Affectionate, the Most Merciful. O Allah! Remove from me my worries and grief.”
