The ḥadīth of ʿĀʾishah proves that no shirt or turban is placed on the deceased. Rather, the shroud pieces are laid one atop the other, the body is set upon them, and then the uppermost cloth is wrapped around him, followed by the middle and finally the lowest. The ends are folded over from the head and the feet, tied, and secured until the body is lowered into the grave. Once the deceased is placed in the grave, those bindings are untied. The scholars explain that the knots are released because the corpse swells after death; if it were left tightly bound, it might burst. Therefore, the ties are undone to prevent this.
In the report of al-Mughīrah ibn Shuʿbah (may Allah be pleased with him), it is related that during the Tabūk campaign the Prophet ﷺ dismounted from his camel, took an idāwah—a small water-skin—and walked on until he vanished into the darkness of the night. He ﷺ was the most modest of people and did not wish anyone to see him while attending to his bodily needs, even if no one could see his nakedness. This is consummate etiquette: when you need to relieve yourself, withdraw until you are completely out of sight—not merely to conceal your ʿawrah, for covering it is obligatory and it is forbidden to uncover it before others, but beyond that, it is preferable that no one see you at all while you are engaged in that act. Such was the practice of the Prophet ﷺ, and his way is the most perfect guidance.
