Now, it cannot get stranger than this ! After calling tattoos anti-shariya, the Darul Uloom Deoband has issued a fatwa (diktat) against dyeing hair black.
The Islamic seminary says that the sharia does not permit one to colour his or her hair black. Some believers had sought the seminary’s views on this issue in response to which the seminary has said that colouring hair black violates the shariah, though one could use henna (mehndi) on the hair.
As per the seminary, the sharia prohibits dyes that leave a layer on the hair as it obstructs water from reaching the roots of hair during wazu (ablution) and make it invalid. On the question of the namaz after colouring the hair, it was allowed to use colour other than black provided it does not contain impure things and does not leave such a layer on the hair that prevents water from reaching the roots.
"Otherwise, the wazu (ablution before offering namaz) shall not be valid and when wazu is not right, namaz shall be invalid," the seminary said. On the use of ammonia-free dyes for the hair, the seminary issued the fatwa that "if the hair get black with that dye, it would be unlawful to apply it, but if the hair get the red colour of henna, it is permissible".
