question #2 Sahih al-Bukhari 5859, Book 77, Hadith 76 : How did the companions of the Prophet demonstrate their reverence and love for him through their actions?

I came to the Prophet (ﷺ) while he was inside a red leather tent, and I saw Bilal taking the remaining
water of the ablution of the Prophet, and the people were taking of that water and rubbing it on their
faces; and whoever could not get anything of it, would share the moisture of the hand of his
companion (and then rub it on his face).
