Surah 65. At-Talaq, Ayah 8

This connects with, and stresses, the fact that all the preceding injunctions are divinely ordained.

Insolent impiety consists not only in the breach of the rites of religion. Even more vital is the defiance of the laws of nature which Allah has made for us. These laws, for us human beings include those which relate to our fellow-beings in society to whom kindness and consideration form the basis of our social duties. Our duties to our families and our children in intimate matters such as were spoken of in the last Section, are as important as any in our spiritual life. Peoples who forgot the moral law in marriage or family life perished in this world and will have no future in the Hereafter. The lessons apply not only to individuals but to whole nations or social groups.

This refers to the present life: apparently the Hereafter is implied in verse 10 below.
