And We have enjoined upon man kindness Unto the parents: with hardship his mother beareth him and with hardship she bringeth him forth, and the bearing of him and the weaning of him is thirty months, until, when he attaineth his full strength and attaineth the age of forty years, he saith: my Lord! grant me that may give thanks for the favour wherewith. Thou hast favoured me and my parents and that may work righteously such as Thou mayest approve; and be Thou good Unto me in my progeny, verily have turned Unto Thee repentant, and verily I am of those who submit.
