The Book of the Prohibited actions
Prohibition of Abusing the Deceased without a valid Legal reason approved by Shari'ah
وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : لَا تَسُبُّوا الْأَمْوَاتَ فَإِنَّهُمْ قَدْ أَفْضَوْا إِلَى مَا قدمُوا . ((رَوَاهُ البُخَارِيّ)).
'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].
