Hadith 17:105
Yazid ibn Harun narrated to us, he said: Sulayman al-Taymi informed us, from Sa'd ibn Mas'ud, from Ibn Abbas, who said: "There is no Muslim who has two parents and wakes up in the morning while he is being good to them, except that Allah opens for him two doors of Paradise. And he does not reach the evening while he is being bad to them, except that Allah opens for him two doors of the Fire. And if one of them is angry with him, Allah is not pleased with him until he (the parent) is pleased with him." He (the narrator) said: I said, "Even if they are unjust?" He said: "Even if they are unjust."
حدثنا يزيد بن هارون قال أخبرنا سليمان التيمي عن سعد بن مسعود عن بن عباس قال ما من مسلم له أبوان فيصبح وهو محسن إليهما إلا فتح الله له بابين من الجنة ولا يمسي وهو مسيء إليهما إلا فتح الله له بابين من النار ولا سخط عليه واحد منهما فيرضى الله عنه حتى يرضى عنه قال قلت وإن كانا ظالمين قال وإن كانا ظالمين
