محمد بن أبي عمير عن هشام بن سالم عن أبي عبد الله عليه السلام قال: جاء رجل إلى النبي صلى الله عليه وآله فقال يا رسول الله: من أبر؟ قال: أمك قال: ثم من؟ قال: عليه السلام: أمك قال ثم من؟ قال: أباك.
22.Muḥammad ibn Abī ʿUmayr narrated from Hishām ibn Sālim, from Abū ʿAbdillāh عليه السلام who said: “A man came to the Prophet صلى الله عليه وعلى آله وسلم and asked, ‘O Messenger of Allah, whom should I be kind to?’ He said, ‘Your mother.’ He asked, ‘Then who?’ He صلى الله عليه وعلى آله وسلم said, ‘Your mother.’ He asked, ‘Then who?’ He said, ‘Your father.’”[1]
[1] In most of the other sources, the third answer is also “Your mother” and then the fourth time he is told to be kind to his father.
