From Sahih Bukhari (Hadith 1244):
Narrated Jabir bin `Abdullah:When my father was martyred, I lifted the sheet from his face and wept and the people forbade me to do so but the Prophet (ﷺ) did not forbid me. Then my aunt Fatima began weeping and the Prophet (ﷺ) said, "It is all the same whether you weep or not. The angels were shading him continuously with their wings till you shifted him (from the field)
