Qur'an, Al-Ahqaf, Surah 46:15
We have ordained humankind to show kindness toward their parents, for in pain their mothers carry them and in pain do they give birth. In thirty months they bear and wean; thus when they attain maturity they may pray, "Lord, inspire us that we may be thankful for the blessings You bestowed upon us and our parents. Kindle within us the desire to do what is upright and pleasing to You. Grant us righteous offspring, Lord. Verily, we turn to You in repentance, surrendering ourselves in earnest."
