Abu Hurayra said, "When someone spits in the presence of people,
let him catch it with his palms so that his spit does not fall on the ground.
When he fasts, he should oil his palm so that the trace of the fast is
not seen on him."
Zayd ibn Thabit reported that 'Umar ibn al-Khattab came to him
to ask to see him one day and he gave him permission while his head was
in the hands of a slavegirl of his who was combing his hair. He removed
his head and 'Umar said to him, 'Let her comb it.' He said, 'Amir al-Mu'minin,
if you were to send for me, I would come to you.' ''Umar said, 'It is my
need.'"
