Are we allowed to dye our hair in Islam?
These two hadiths contradict each other
Dawud :: Book 34 : Hadith 4210
Narrated Abdullah ibn Mas'ud:
The Prophet of Allah (peace_be_upon_him) disliked ten things: Yellow colouring, meaning khaluq, dyeing grey hair, trailing the lower garment, wearing a gold signet-ring, a woman decking herself before people who are not within the prohibited degrees, throwing dice, using spells except with the Mu'awwidhatan, wearing amulets, withdrawing the penis before the semen is discharged, in the case of a woman who is wife or not a wife, and having intercourse with a woman who is suckling a child; but he did not declare them to be prohibited.
This one says prophet did not like dyeing hair.
Bukhari :: Book 7 :: Volume 72 :: Hadith 786
Narrated Abu Huraira :
The Prophet said, "Jews and Christians do not dye their hair so you should do the opposite of what they do.
This one tells us to dye our hair.
Also if dyeing is possible then what colours are allowed?
