Concise Quran Commentary
Allah is the One Who made you successors of those whom came before you on earth, so that you inhabit it after them. He has raised some of you in rank over others – in terms of physical form, livelihood and other aspects – in order to test you through what He has given you. Your Lord, O Messenger, is quick in delivering justice, since anything that is approaching is close. And He is also Forgiving and Compassionate towards those of His servants who repent to Him.
