Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن عائشة رضي الله عنها قالت: قال رسول الله صلى الله عليه وسلم : "لا تسبوا الأموات فإنهم قد أفضوا إلى ما قدموا". ((رواه البخاري)).
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].
