Like a brick in the societal structure, family is a large part of Islamic principles. The Holy Quran, articles, rules, and laws on family are found in many verses and chapters. Islam commands love and respect to prevail within the family. In this respect, the Quran depicts the relationship between husband and wife, saying:  

“And among His signs is that He created for you mates from among yourselves that you dwell in peace together and that He put love mercy between your hearts. Verily in that are signs for those reflect.” Surah Ar-Rum Verse 21.  

The Quran also emphasizes the relationship between parents and children. It puts down that the relationship is a mutual cooperation and helps extend the strong to the weak. For example, in infancy, children need the care of their parents. In the same manner, in their old age, the parents need the support of their children. One cannot find a better expression of the relationship than the dictate of Allah in the Quran: 

“Your Allah had decreed that you worship none but Him and that you be kind to your parents. When one or both of them attain old age in your life, say not to them a word of contempt, nor repel them, but address them in terms of honor.” 

“And lower into them the wing of submission through mercy and say: “My Lord! Have mercy on them both as they did care for me when I was little.” Surah Al-Isra, Verse 23-24
