Al-Ahqaf 46:15 ووصينا الانسان بوالديه احسانا حملته امه كرها ووضعته كرها وحمله وفصاله ثلاثون شهرا حتى اذا بلغ اشده وبلغ اربعين سنة قال رب اوزعني ان اشكر نعمتك التي انعمت علي وعلى والدي وان اعمل صالحا ترضاه واصلح لي في ذريتي اني تبت اليك واني من المسلمين ١٥

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."
