Hud · 11:18

18. 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.
