﴿ وَكَذَٰلِكَ نُفَصِّلُ ٱلْءَايَٰتِ وَلَعَلَّهُمْ يَرْجِعُونَ ﴾

“And thus clearly do We spell out these messages; and [We do it] so that they [who have sinned] might return [unto Us].”

The next verse 174 said: وَكَذَٰلِكَ نُفَصِّلُ الْآيَاتِ وَلَعَلَّهُمْ يَرْ‌جِعُونَ ﴿174﴾ "And this is how we elaborate the verses, so that they may return." That is, Allah has made His signs clear through His elaborate verses to facilitate people to turn back to their pledge and acknowledge Him as their Lord. Any one applying his reason can find the Truth and save himself from everlasting punishment.
