Sunan Abi Dawud Book 35, Hadith 23
When the Prophet of Allah (ﷺ) conquered Makkah. The people of Makkah began to bring their boys and he would invoke a blessing on them and rub their heads. I was brought, but as I had been perfumed with khaluq, he did not touch me because of the khaluq.
The Prophet (ﷺ) said: The angels do not come near three: the dead body of the unbeliever, one who smears himself with khaluq, and the one who is sexually defiled except that he performs ablution.
A man came to the Messenger of Allah (ﷺ) and he had the mark of yellowness (of saffron). The Prophet (peace be upon him rarely mentioned a thing which he disliked before a man. When he went away, he said: Would that you tell this man that he should wash this off him.
