An-Nisa' - 4:50

انظُرْ كَيفَ يَفْتَرُونَ عَلَى اللّهِ الكَذِبَ وَكَفَى بِهِ إِثْمًا مُّبِينًا
[4:50]
See how they forge the lie against Allah, and this is sufficient as a manifest sin.
Behold! how they invent a lie against Allah! but that by itself is a manifest sin!
See, how they invent lies about Allah! That of itself is flagrant sin.
