Riyad as-Salihin

Jabir bin 'Abdullah (May Allah be pleased with them) reported: The dead body of my father, who was mutilated by the enemy, was brought and placed before the Prophet (ﷺ). I got up to uncover his face but the people stopped me, and the Prophet (ﷺ) said, "The angels continue to cover him with their wings."

[Al-Bukhari and Muslim].
