And We have enjoined upon man, to his parents, good treatment. His mother carried him with hardship and gave birth to him with hardship, and his gestation and weaning [period] is thirty months. [He grows] until, when he reaches maturity and reaches [the age of] forty years, he says, "My Lord, enable me1 to be grateful for Your favor which You have bestowed upon me and upon my parents and to work righteousness of which You will approve and make righteous for me my offspring. Indeed, I have repented to You, and indeed, I am of the Muslims."
Translation: Saheeh International (English)
1 Literally, "gather within me the utmost strength and ability."
And I commanded man with emphasis that he should be kind to his parents and that he should be righteous towards them in their lifetime and after their death with what does not oppose the sacred law. And in particular his mother who carried him with difficulty and gave birth to him with difficulty. And the length of his gestation period in which he remained and the beginning of his weaning is thirty months. Until when he reaches the completion of his mental and physical strength, he says: “My Lord, inspire me to thank You for Your favour you have done to me and my parents, and inspire me to do good actions which please you, and accept them from me. And correct my children for me. I have repented to You from my sins and I am amongst those who submit to Your obedience and surrender to Your commands”.
