What is the truth behind the circulating story of a woman who died without ever having prayed a single prostration to Allah, and who died while adorned, and what caused her face to blacken during her washing and burial?

Blackness of the face upon death may be interpreted as the deceased seeing angels and what displeases him at the extraction of his soul, causing him to recoil and his face to darken. The throes of death are difficult except for a Muslim. The blackness of the aforementioned woman's face might be due to her abandoning prayer and dying immodestly adorned. A Muslim must conceal what he sees of bad states of the deceased, as stated in the Hadith: "Whoever washes a dead person and conceals [his faults] will be forgiven forty major sins."
