وَيَهْدِيَكُمْ سُنَنَ الَّذِينَ مِن قَبْلِكُمْ

(And to show you the ways of those before you,) meaning their righteous ways and how to adhere to the commandments that He likes and is pleased with.

وَيَتُوبَ عَلَيْكُمْ

Sequence

Mentioned in the previous verses were details of injunctions. Now, in the present verses, Allah Almighty points to his blessings and favours saying that your being obligated with these injunctions is for your own good, even though you may not be able to understand its manifestation in details. Then, along with it, there is the motivation to follow the divine injunctions. Finally, there is the message of alert against the evil intentions of the misguided who wish ill of you and would like you to stray far away from the straight path.
