Surah Az-Zumar (The Successive Groups), Verse 7

اِنْ تَكْفُرُوْا فَاِنَّ اللّٰهَ غَنِیٌّ عَنْكُمْ وَلَا یَرْضٰی لِعِبَادِهِ الْكُفْرَ وَاِنْ تَشْكُرُوْا یَرْضَهُ لَكُمْ وَلَا تَزِرُ وَازِرَةٌ وِّزْرَ اُخْرٰی ثُمَّ اِلٰی رَبِّكُمْ مَّرْجِعُكُمْ فَیُنَبِّئُكُمْ بِمَا كُنْتُمْ تَعْمَلُوْنَ اِنَّهٗ عَلِیْمٌۢ بِذَاتِ الصُّدُوْرِ ۟

In takfuroo fa innal laaha ghaniyyun 'ankum; wa laa yardaa li'ibaadihil kufra wa in tashkuroo yardahu lakum; wa laa taziru waaziratunw wizra ukhraa; summa ilaa Rabikum marji'ukum fa-yunabbi'ukum bimaa kuntum ta'maloon; innahoo 'aleemum bizaatissudoor

“If ye reject (Allah), Truly Allah hath no need of you; but He liketh not ingratitude from His servants: if ye are grateful, He is pleased with you. No bearer of burdens can bear the burden of another. In the end, to your Lord is your Return, when He will tell you the truth of all that ye did (in this life). For He knoweth well all that is in (men's) hearts.”

Quran 39:7 (Yusuf Ali Translation)
