The Quran

164

قُل أَغَيرَ اللَّهِ أَبغي رَبًّا وَهُوَ رَبُّ كُلِّ شَيءٍ ۚ وَلا تَكسِبُ كُلُّ نَفسٍ إِلّا عَلَيها ۚ وَلا تَزِرُ وازِرَةٌ وِزرَ أُخرىٰ ۚ ثُمَّ إِلىٰ رَبِّكُم مَرجِعُكُم فَيُنَبِّئُكُم بِما كُنتُم فيهِ تَختَلِفونَ

Muhammad Asad

Say: "Am I, then, to seek a sustainer other than God, when He is the Sustainer of all things?" And whatever [wrong] any human being commits rests upon himself alone; and no bearer of burdens shall be made to bear another's burden.¹ And, in time, unto your Sustainer you all must return: and then He will make you. [truly] understand all that on which you were wont to differ.²

This statement - which is also found in 17:15, 35:18. 39:7 and 53:38 - constitutes a categorical rejection of the Christian doctrines of "original sin" and "vicarious atonement". For the wider ethical implications of this statement, see 53:38, where it occurs for the first time in the chronological order of revelation.
See surah 2, note 94.
