إِنَّمَا تَعْبُدُونَ مِن دُونِ ٱللَّهِ أَوْثَٰنًۭا وَتَخْلُقُونَ إِفْكًا ۚ إِنَّ ٱلَّذِينَ تَعْبُدُونَ مِن دُونِ ٱللَّهِ لَا يَمْلِكُونَ لَكُمْ رِزْقًۭا فَٱبْتَغُوا۟ عِندَ ٱللَّهِ ٱلرِّزْقَ وَٱعْبُدُوهُ وَٱشْكُرُوا۟ لَهُۥٓ ۖ إِلَيْهِ تُرْجَعُونَ
Ye serve instead of Allah only idols, and ye only invent a lie. Lo! those whom ye serve instead of Allah own no provision for you. So seek your provision from Allah, and serve Him, and give thanks unto Him, (for) unto Him ye will be brought back.
Surah Al-Ankaboot(29:17)
