Surah Al-A'raf 7:55 — translation and meaning

O believers, call on your Lord with complete humility, silently and in private, sincere in your prayer, not showing off, and not worshipping others along with Allah in your prayers. He does not love those who overstep the limits in their prayers; and one of the worst ways someone can do this is by invoking others besides Him, as the idolaters do.
