Since mothers exert giant efforts and suffer insensitive ordeals for sake of their sons, the Islamic Sharia has conferred upon them with greater deal of obligatory care and piety:
Imam as-Sadiq (a) narrated that, once, a man asked the Prophet (s), 'whom must I treat piously first, God's Messenger?' The Prophet (s) answered, 'you must first treat your mother piously.' 'Then?' asked the man. 'Your mother,' answered the Prophet (s). 'Then?' asked the man. 'Your mother,' answered the Prophet (s). 'Then?' asked the man. 'Your mother,' answered the Prophet (s). 'Then?' asked the man. 'Then comes your father,' answered the Prophet (s).
Ibrahim bin Muhazzim narrated:
After I had left Imam as-Sadiq, one night, I came to my house in Medina and quarreled with my mother who was living with me. The next morning, I visited him after I had offered the Fajr Prayer. He addressed to me, before I said anything, "Abu Muhazzim, what was your matter with Khalida? Last night, you addressed bad words to her. You should have known that her womb was the abode in which you resided, her lap was the cradle in which you slept, and her breast was the bowl from which you drank."
"Yes," I answered, "I have known all these."
"Then," said the Imam (a), "You should not be coarse with her any more."
Imam as-Sejjad (a) said in his Treatise of Rights:
"The right of your mother is that you know that she carried you where no one carries anyone, she gave to you the fruit of her heart that which no one gives to anyone, and she protected you with her hearing, sight, hand, leg, hair, and skin as well as all her organs. She was highly delighted, happy, eager, and enduring the harm, pains, heaviness, and grief until the hand of power saved her from you and took you out to this earth. She did not care if she went hungry
