From the Holy Qur’an:Chapter 11 - Hood P2/2

“My Lord is Most Merciful, Kind.” Worship God, you have no other god beside Him. Your Lord will surely recompense everyone for their works. He is fully Cognizant of everything they do. Therefore, continue on the path you have been enjoyed to follow, together with those who repented with you, and do not transgress. You shall observe the Contact Prayers (Salat) at both ends of the day, and during the night. The righteous works wipe out the evil works. You shall steadfastly persevere, for God never fails to recompense the righteous.
