Anas bin Maalik R.A. reports: "I did not count more than fourteen white hair on the head and beard of Rasulullah (Sallallahu alaihe wasallam)".
Sayyidina Rasulullah (Sallallahu alaihe wasallam) had very few white hair. There is some disagreement on the actual number. In this narration fourteen hairs are mentioned. In others, seventeen, eighteen, and in some, twenty white hairs are mentioned. This is a minor disagreement. The other ahaadith may have been related at different periods. A difference in the counting may also be possible.
