“Clothe yourselves in white,

Samurah ibn Jundab reported: The Messenger of Allah صلى الله عليه وسلم said, “Clothe yourselves in white, for indeed it is cleaner and more pure; and shroud your dead in it.”

عَنْ سَمُرَةَ بْنِ جُنْدَبٍ قَالَ  قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْبَسُوا الْبَيَاضَ فَإِنَّهَا أَطْهَرُ وَأَطْيَبُ وَكَفِّنُوا فِيهَا مَوْتَاكُمْ

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
