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 me to be grateful for Your favour 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.”
The Qur’an, Surah Al-‘Ahqaaf (Chapter of the wind curved sand hills) 46:15
Abu Huraira reported that a person came to Allah’s Messenger (may peace be upon him) and said: Who among the people is most deserving of a fine treatment from my hand? He said: Your mother. He again said: Then who (is the next one)? He said: Again it is your mother (who deserves the best treatment from you). He said: Then who (is the next one)? He (the Holy Prophet) said: Again, it is your mother. He (again) said: Then who? Thereupon he said: Then it is your father. In the hadith transmitted on the authority of Qutalba, there is no mention of the word “the people”.
(Bukhari Book 32, Number 6180)
Abu Huraira reported that a person said: Allah’s Messenger, who amongst the people is most deserving of my good treatment? He said: Your mother, again your mother, again your mother, then your father, then your nearest relatives according to the order (of nearness).
(Bukhari Book 32, Number 6181)
The Prophet Muhammad said, may Allah’s peace and blessings be upon him: Your Heaven lies under the feet of your mother.
