Hazrat Yazid bin Abi Ziyad (may Allah have mercy on him) narrates that Hazrat Abdur Rahman bin Abi Laila (may Allah have mercy on him) was invited to a wedding one night, where he applied a fragrance that had a yellowish tint. In the morning, there was a yellowish color in his beard. He washed it, but it did not come off, so he washed it again with soap.
