The Precious Pearl in the Rulings of Dress and Adornment

4: The Virtue of Gray Hair and the Ruling on Changing It Without Using Black Regarding the virtue of gray hair, the Messenger of Allāh ﷺ said: “Whoever grows gray hair in Islam, it will be a light for him on the Day of Resurrection.” [As-Silsilah Aṣ-Ṣaḥīḥah 3/248] He also said: “Gray hair is the light of the believer. No man grows gray hair in Islam except that he receives a reward for every gray hair, and it raises his rank.” [As-Silsilah Aṣ-Ṣaḥīḥah 3/247] The Prophet ﷺ also instructed changing gray hair, saying “Do not imitate the Jews and Christians; do not colour it black.” [As-Silsilah Aṣ-Ṣaḥīḥah 3/248] He ﷺ further said: “The best way to change gray hair is using katam (dye) and henna.” [Ṣaḥīḥ Ibn Ḥibbān 5474] And: “Change this (gray hair) with something, and avoid black.” [Ṣaḥīḥ Muslim 2102]
