Surah Hud — Ayah 18 (11:18)
وَمَنۡ أَظۡلَمُ مِمَّنِ ٱفۡتَرَىٰ عَلَى ٱللَّهِ كَذِبًاۚ أُوْلَٰٓئِكَ يُعۡرَضُونَ عَلَىٰ رَبِّهِمۡ وَيَقُولُ ٱلۡأَشۡهَٰدُ هَٰٓؤُلَآءِ ٱلَّذِينَ كَذَبُواْ عَلَىٰ رَبِّهِمۡۚ أَلَا لَعۡنَةُ ٱللَّهِ عَلَى ٱلظَّٰلِمِينَ ١٨
English translation (Saheeh International)
And who is more unjust than he who invents a lie about Allāh? Those will be presented before their Lord, and the witnesses will say, "These are the ones who lied against their Lord." Unquestionably, the curse of Allāh is upon the wrongdoers
Brief commentary
No one is a greater wrongdoer than someone who makes up a lie about Allah, associating a partner or a son with Him. Those who make up lies about Allah will be brought before their Lord on the Day of Judgement to be asked about their actions, and the witnesses against them, from among the angels and the messengers, will say that they were the ones who lied about Allah by attributing a partner or son to Him. Allah’s depriving them of His mercy is due to their lies about Allah.
