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. Until when he reaches maturity and reaches the age of forty years, he says
Rabbi awzi’nee an ashkura ni’mataka allatee an’amta ‘alayya wa’ala walidayya waan a’mala salihan tardahu waaslih lee fee thurriyyatee innee tubtu ilayka wa-innee mina almuslimeen
“My Lord, grant me strength and ability to be grateful for Your favor which You have bestowed upon me and upon my parents and to do righteous [deeds] that will please You and make righteous for me my offspring. Indeed, I have repented to You, and indeed, I am of the Muslims.”
Those are the ones from whom We will accept the best of what they did and overlook their evil deeds, [their being] among the companions of Paradise. [That is] the promise of truth which they had been promised.
