صحيح مسلم 263

It is narrated on the authority of 'Abdullah b. Amr b. al-'As that the Messenger of Allah (ﷺ) observed:Abusing one's parents is one of the major sins. They (the hearers) said: Messenger of Allah, does a man abuse his parents too? He (the Holy Prophet) replied: Yes, one abuses the father of another man, who in turn abuses his father. One abuses his mother and he in turn abuses his (the former's) mother

Rapporté par ‘Abdullah b. Amr b. al-‘As : Le Messager d’Allah ﷺ a dit : « Insulter ses parents fait partie des grands péchés. » Ils ont demandé : « Messager d’Allah, est-ce qu’un homme insulte ses propres parents ? » Il a répondu : « Oui, il insulte le père d’un autre homme, qui insulte alors son père. Il insulte la mère d’un autre, qui insulte alors sa mère. »
