Aya number 5 of surat At-Talaq
بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ
ذَٰلِكَ أَمْرُ اللَّهِ أَنْزَلَهُ إِلَيْكُمْ وَمَنْ يَتَّقِ اللَّهَ يُكَفِّرْ عَنْهُ سَيِّئَاتِهِ وَيُعْظِمْ لَهُ أَجْرًا 
Translation: English - Sahih International
That is the command of Allah , which He has sent down to you; and whoever fears Allah - He will remove for him his misdeeds and make great for him his reward.
