Surah 39

Surah 39:3

"Is it not (a fact) that pure religion is for God (alone)? But those who take allies instead of Him – ’We only serve them so that they may bring us near to God in intimacy’ – surely God will judge between them concerning their differences. Surely God does not guide anyone who is a liar (or) ungrateful."

– But those who take allies instead of Him

The tendency of people to give loyalty to other gods, or idols (v. 17), is an important theme in this sūra.
