To maintain natural appearance and avoid unnecessary changes for vanity/prideful display of beauty

This hadith is about dyeing one's hair in Islam. It is narrated by Ibn Sirin who asked Anas b. Malik if the Prophet Muhammad ever dyed his hair, to which he replied that he had not reached a stage where it was necessary for him to do so yet, but Abu Bakr did dye his hair with henna. This suggests that while it is permissible to dye one's hair in Islam, it should only be done when absolutely necessary and not as a form of vanity or pride. The lesson here is that Muslims should strive to maintain their natural appearance and avoid any unnecessary changes or alterations for the sake of vanity or prideful display of beauty.
