Sahih Muslim, 263

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. »

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
