And We have commanded man to be good towards parents; his mother bore him with hardship, and delivered him with hardship; and carrying him and weaning him is for thirty months; until when he* reached maturity and became forty years of age, he said, “My Lord! Inspire me to be thankful for the favours you bestowed upon me and my parents, and that I may perform the deeds pleasing to You, and keep merit among my offspring; I have inclined towards you and I am a Muslim.” (* This verse was revealed concerning S. Abu Bakr – the first caliph, R. A. A)
