«يُخَادِعُونَ اللَّهَ وَهُوَ خَادِعُهُمْ»
They seek to deceive Allah, while He recompenses their deception. (Al-Nisāʾ 4:142)
Both parts are declarative in wording and sense. The first reports their attempt; the second answers it with the divine response. The repeated semantic field of khidāʿ, together with a reversal of roles, supplies an intelligible link.
The second remains a distinct proposition rather than a repetition of the first, so coordination serves a purpose.
