'Aishah (May Allah be pleased with her) said:
The Messenger of Allah ﷺ said, "Do not abuse the dead, because they have attained that which they had forwarded (i.e., their deeds, good or bad)."

[Al-Bukhari].

وعن عائشة رضي الله عنها قالت: قال رسول الله ﷺ : "لا تسبوا الأموات فإنهم قد أفضوا إلى ما قدموا". ((رواه البخاري)).
