What is the link between verse 237 of Surat Al-Baqarah, which deals with the rulings of divorce, and verse 238, which speaks about the rulings of prayer?

The science of munasabat (Qur'anic coherence) is a noble discipline concerned with showing the connections between verses and chapters to demonstrate the wisdom behind the Qur'anic arrangement. It is a field based on scholarly effort (ijtihad). Some scholars have mentioned that the appropriateness of the verse about prayer ("Be watchful over the prayers") after the verse about forgiveness in divorce is that forgiveness requires a spiritual remedy, which is prayer. Prayer assists in attaining piety and noble character. Thus, after clarifying the rights of people, it then points to the rights of Allah. Alternatively, the preceding verses dealt with the rights of creation and disputes, so the verse about prayer came to guide towards what achieves a good connection with Allah, the Almighty.
