The Holy Quran, Chapter Abasa - عبس

قُلْ أَغَيْرَ اللّهِ أَبْغِي رَبّاً وَهُوَ رَبُّ كُلِّ شَيْءٍ وَلاَ تَكْسِبُ كُلُّ نَفْسٍ إِلاَّ عَلَيْهَا وَلاَ تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَى ثُمَّ إِلَى رَبِّكُم مَّرْجِعُكُمْ فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ

Say: Shall I seek another than Allah for Lord, when He is Lord of all things? Each soul earneth only on its own account, nor doth any laden bear another's load. Then unto your Lord is your return and He will tell you that wherein ye differed.
