It is narrated from Hazrat Hakam bin Amr that once my brother Rafi' bin Amr and I presented ourselves before the Commander of the Faithful, Hazrat Umar Farooq. I had dyed my hair with henna, and my brother had used a yellow dye. Hazrat Umar said to me, "This is the dye of Islam," and to my brother Rafi', he said, "This is the dye of faith."
