Al-Ahqaf - 46:15

And We have enjoined on man doing of good to his parents; with trouble did his mother bear him and with trouble did she bring him forth; and the bearing of him and the weaning of him was thirty months; until when he attains his maturity and reaches forty years, he says: My Lord! grant me that I may give thanks for Thy favor which Thou hast bestowed on me and on my parents, and that I may do good which pleases Thee and do good to me in respect of my offspring; surely I turn to Thee, and surely I am of those who submit.

We have enjoined on man kindness to his parents: In pain did his mother bear him, and in pain did she give him birth. The carrying of the (child) to his weaning is (a period of) thirty months. At length, when he reaches the age of full strength and attains forty years, he says, "O my Lord! Grant me that I may be grateful for Thy favour which Thou has bestowed upon me, and upon both my parents, and that I may work righteousness such as Thou mayest approve; and be gracious to me in my issue. Truly have I turned to Thee and truly do I bow (to Thee) in Islam."

And We have commended unto man kindness toward parents. His mother beareth him with reluctance, and bringeth him forth with reluctance, and the bearing of him and the weaning of him is thirty months, till, when he attaineth full strength and reacheth forty years, he saith: My Lord! Arouse me that I may give thanks for the favour wherewith Thou hast favoured me and my parents, and that I may do right acceptable unto Thee. And be gracious unto me in the matter of my seed. Lo! I have turned unto Thee repentant, and lo! I am of those who surrender (unto Thee).
