Muhammad bin Sirin says that Sayyiduna Anas bin Malik (may Allah be pleased with him) was asked about the dyeing of the hair of the Messenger of Allah (peace and blessings be upon him). He said that the Messenger of Allah (peace and blessings be upon him) had only a few white hairs, but Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them both) used to dye their hair with a mixture of henna and katam after him. Sayyiduna Abu Bakr (may Allah be pleased with him) brought his father, Sayyiduna Abu Quhafa (may Allah be pleased with him), to the Prophet (peace and blessings be upon him); this was on the day of the conquest of Makkah. Sayyiduna Abu Bakr (may Allah be pleased with him) carried him and placed him before the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: If you had let the elder remain in his house, we would have gone to him ourselves to honor Abu Bakr. Then Abu Quhafa accepted Islam. His beard and head hair were white like the thaghamah plant, so the Prophet (peace and blessings be upon him) said: Change the color of these two, but avoid black.
