Duas from the Ahadeeth
أَسْتَغْفِرُ اللَّهَ الَّذِي لاَ إِلَهَ إِلاَّ هُوَ الْحَىُّ الْقَيُّومُ وَأَتُوبُ إِلَيْهِ
“I beg forgiveness of Allah, the deity other than Whom there is no God. He is alive and everlasting and I seek repentance unto Him.” (Abu Dawood)
اللَّهُمَّ اغْفِرْ لِي مَا أَخْطَأْتُ وَمَا تَعَمَّدْتُ ، وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ ، وَمَا جَهِلْتُ وَمَا تَعَمَّدْتُ
“Oh Allah! Forgive those sins of mine that I committed in error and the ones I committed deliberately, and the ones I did privately, and the ones that I did publically, and the ones I committed erroneously, and the ones I committed deliberately.” (Ahmad)
اللَّهُمَّ اغْسِلْ عَنِّي خَطَايَاىَ بِمَاءِ الثَّلْجِ وَالْبَرَدِ، وَنَقِّ قَلْبِي مِنَ الْخَطَايَا، كَمَا نَقَّيْتَ الثَّوْبَ الأَبْيَضَ مِنَ الدَّنَسِ، وَبَاعِدْ بَيْنِي وَبَيْنَ خَطَايَاىَ كَمَا بَاعَدْتَ بَيْنَ الْمَشْرِقِ وَالْمَغْرِبِ
“Oh Allah! Wash away from me my sins with ice and hail water and purify my heart from wrong doings, as you cleanse a white cloth from dirt; and place distance between me and my sins as much as you have kept between east and west.” (Bukhari)
