Surah Al-Hadid (The Iron), Verse 28

یٰۤاَیُّهَا الَّذِیْنَ اٰمَنُوا اتَّقُوا اللّٰهَ وَاٰمِنُوْا بِرَسُوْلِهٖ یُؤْتِكُمْ كِفْلَیْنِ مِنْ رَّحْمَتِهٖ وَیَجْعَلْ لَّكُمْ نُوْرًا تَمْشُوْنَ بِهٖ وَیَغْفِرْ لَكُمْ وَاللّٰهُ غَفُوْرٌ رَّحِیْمٌ ۟

Yaaa ayyuhal lazeena aamaanut taqullaaha wa aaminoo bi Rasoolihee yu'tikum kiflaini mir rahmatihee wa yaj'al lakum nooran tamshoona bihee wa yaghfir lakum; wallaahu Ghafoorur Raheem

“O ye that believe! Fear Allah, and believe in His Messenger, and He will bestow on you a double portion of His Mercy: He will provide for you a Light by which ye shall walk (straight in your path), and He will forgive you (your past): for Allah is Oft-Forgiving, Most Merciful.”
