FROM ‘Abdullah bin’ Umar, the Prophet sallallaahu ‘alaihi wa sallam said, “Uban is light for the believer. It is not someone with gray hair in his gray Islam but each will be counted as a virtue and rank will be higher,” (HR. Al Bayhaqi in Syu’abul Faith. Shaykh Al Albani in Al-Jami ‘Ash Shogir said that this hadeeth hasan).
Muhammad ibn Hibbaan At Tamimi rahimahullah, or better known as Ibn Hibbaan in his Saheeh book mentioned the discussion Hadith relates that Allah will record the good and eliminate errors and will exalt a Muslim because her gray hair guard in the world.
Then Ibn Hibbaan bring other hadits. From Abu Hurairah, the Prophet sallallaahu ‘alaihi wa sallam said, “Do not repeal a gray hair because gray hair is light on the Day of Judgement. Anyone gray in Islam though a piece, then with gray hair that will be recorded for him a favor, with shades of gray that will be eliminated one mistake, also with him will be elevated one degree,” (HR. Ibn Hibbaan in his Saheeh. Shoaib Shaikh Al Arnauth say that sanad hasan hadeeth).
In 2012, Ismael Galvan of the Museo Nacional de Ciencias Naturales, Spain conducted research on gray. From the results of the researchers, gray hair is a sign you will have a long and healthy life. But the bad news for those who have red hair, because it is related to higher levels of cancer.
“Melanin skin, hair and fur in humans is the same type. This limits the knowledge on the physiological consequences of pigmentation,” said Galvan.
Gray hair signifies the absence of melanin. That is, gray hair is a sign of a healthy life.
“Far from related signs of aging, gray indicates good conditions,” he concluded. So, your hair has changed?
