The Quran

أَفتَرىٰ عَلَى اللَّهِ كَذِبًا أَم بِهِ جِنَّةٌ ۗ بَلِ الَّذينَ لا يُؤمِنونَ بِالآخِرَةِ فِي العَذابِ وَالضَّلالِ البَعيدِ

Muhammad Asad

Does he [knowingly] attribute his own lying inventions to God - or is he a madman?" Nay, [there is no madness in this Prophet -] but they who will not believe in the life to come are [bound to lose themselves] in suffering and in a profound aberration.¹

Lit., "remote aberration". (For the Qur'anic use of the term dalal - lit., "error" or "going astray" - in the sense of "aberration", see 12:8 and 95.) The construction of this phrase points definitely to suffering in this world (in contrast with the suffering in the hereafter spoken of in verse 5 above): for whereas the concept of "aberration" is meaningless in the context of the life to come, it has an obvious meaning in the context of the moral and social confusion - and, hence, of the individual and social suffering - which is the unavoidable consequence of people's loss of belief in the existence of absolute moral values and, thus, in an ultimate divine judgment on the basis of those values.
