Abdullah ibn Masood Allah be pleased with him narrates that the prophet of Allah, Allah send peace and blessings on him used to make the following prayer:
Oh Allah! I ask you (to bestow me with) guidance, God consciousness purity and independence.
عَنْ عَبْدِ اللَّهِ عَنِ النَّبِىِّ -صلى الله عليه وسلم- أَنَّهُ كَانَ يَقُولُ
اللَّهُمَّ إِنِّى أَسْأَلُكَ الْهُدَى وَالتُّقَى وَالْعَفَافَ وَالْغِنَى
(رواه مسلم، ح/٧٠٧٩)

One who repents from sin is like one who has no sin
