Sura 57 Al-Hadid (The Iron), aya 28

1. يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ وَآمِنُوا بِرَسُولِهِ يُؤْتِكُمْ كِفْلَيْنِ مِنْ رَحْمَتِهِ وَيَجْعَلْ لَكُمْ نُورًا تَمْشُونَ بِهِ وَيَغْفِرْ لَكُمْ ۚ وَاللَّهُ غَفُورٌ رَحِيمٌ

   O you who have believed, fear Allah and believe in His Messenger; He will (then) give you a double portion of His mercy and make for you a light by which you will walk and forgive you; and Allah is Forgiving and Merciful.
