Musannaf Ibn Abi Shaybah 26630 — Dyeing with henna

It is narrated from Uthman bin Mawhab; he said: I went in to Sayyidah Umm Salamah (may Allah be pleased with her), and she brought out and showed me one of the hairs of the Messenger of Allah (peace and blessings be upon him), dyed with henna and katam.
