Al Baqarah

كَذَلِكَ يُبَيِّنُ اللّهُ لَكُمْ آيَاتِهِ لَعَلَّكُمْ تَعْقِلُونَ

242. "Thus Allah makes clear to you His Signs, so that you might understand."

In this verse, which is the last verse from the group of verses about divorce, the Qur'an says:

It is evident that the purpose of the Qur'anic phrase / la'allakum ta'qilun / ' so that you might understand ' is that the intention of movement from the beginning should be towards the destination of 'action'; else, mere contemplation upon ordinances and understanding them, with no deed, will be fruitless.
