Tawhid (Monotheism and Oneness of Allah)

وَقُلِ ٱلْحَمْدُ لِلَّهِ ٱلَّذِى لَمْ يَتَّخِذْ وَلَدًا وَلَمْ يَكُن لَّهُۥ شَرِيكٌ فِى ٱلْمُلْكِ وَلَمْ يَكُن لَّهُۥ وَلِىٌّ مِّنَ ٱلذُّلِّ ۖ وَكَبِّرْهُ تَكْبِيرًۢا

And say, "Praise to Allāh, who has not taken a son and has had no partner in [His] dominion and has no [need of a] protector out of weakness; and glorify Him with [great] glorification."

وَيُنذِرَ ٱلَّذِينَ قَالُوا۟ ٱتَّخَذَ ٱللَّهُ وَلَدًا

And to warn those who say, "Allāh has taken a son".
