The Prophet ﷺ said: Wear your white garments, for they are among your best garments, and shroud your dead in them. Among the best types of collyrium you use is antimony (ithmid): it clears the vision and makes the hair sprout. (Using translation from Abū Dāʾūd 3878)   

قَالَ النَّبِيُّ ﷺ الْبَسُوا مِنْ ثِيَابِكُمُ الْبِيضَ وَكَفِّنُوا فِيهَا مَوْتَاكُمْ وَمِنْ خَيْرِ أَكْحَالِكُمُ الْإِثْمِدُ؛ إِنَّهُ يَجْلُو الْبَصَرَ وَيُنْبِتُ الشَّعْرَ
