Offer genuine remorse, not a rushed sorry. Sincere turning back is where the return begins.

التحريم

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ تُوبُوٓاْ إِلَى ٱللَّهِ تَوۡبَةࣰ نَّصُوحًا عَسَىٰ رَبُّكُمۡ أَن يُكَفِّرَ عَنكُمۡ سَيِّـَٔاتِكُمۡ وَيُدۡخِلَكُمۡ جَنَّٰتࣲ تَجۡرِي مِن تَحۡتِهَا ٱلۡأَنۡهَٰرُ يَوۡمَ لَا يُخۡزِي ٱللَّهُ ٱلنَّبِيَّ وَٱلَّذِينَ ءَامَنُواْ مَعَهُۥۖ نُورُهُمۡ يَسۡعَىٰ بَيۡنَ أَيۡدِيهِمۡ وَبِأَيۡمَٰنِهِمۡ يَقُولُونَ رَبَّنَآ أَتۡمِمۡ لَنَا نُورَنَا وَٱغۡفِرۡ لَنَآۖ إِنَّكَ عَلَىٰ كُلِّ شَيۡءࣲ قَدِيرࣱ‏

Believers, turn to God in sincere repentance. Your Lord may well cancel your bad deeds for you and admit you into Gardens graced with flowing streams, on a Day when God will not disgrace the Prophet or those who have believed with him. With their lights streaming out ahead of them and to their right, they will say, ‘Lord, perfect our lights for us and forgive us: You have power over everything.’
