Samurah (May Allah be pleased with him) reported:
Messenger of Allah ﷺ said, 'Wear white clothes because they are the purest and they are closest to modesty; and shroud the dead in it."

[An- Nasa'i and Al-Hakim].

وعن سمرة رضى الله عنه قال: قال رسول الله ﷺ :
"إلبسوا البياض؛ فإنها أطهر وأطيب، وكفنوا فيها موتاكم" .
