A man from among the Companions of the Prophet [SAW] who was called 'Ubaid said: "The Messenger of Allah [SAW] used to forbid too much of Al-Irfah." Ibn Buraidah was asked what too much of Al-Irfah meant, and he said: "It includes combing the hair."

The Messenger of Allah [SAW] liked to start on the right whenever possible; when purifying himself, when putting on his shoes, and when combing his hair.

The Messenger of Allah [SAW] said: "The Jews and the Christians do not dye their hair, so be different from them."

"Abu Quhafah was brought to the Messenger of Allah [SAW] and his head and beard were white like the Thaghamah. The Prophet [SAW] said: 'Change this, or dye it.'"

"I saw Ibn 'Umar dyeing his beard yellow and I asked him about that. 'He said: "I saw the Prophet [SAW] dye his beard yellow."

"The Prophet [SAW] used to wear Sibtiyyah sandals and dye his beard yellow with Wars and saffron." And Ibn 'Umar used to do that.

"I heard Mu'awiyah say, when he was on the Minbar in Al-Madinah, and he brought out a hairpiece from his sleeve: 'O people of Al-Madinah, where are your knowledgeable ones? I heard the Messenger of Allah [SAW] forbid such things as this, and he said: "The Children of Israel were destroyed when their women started to wear things like this."

"Mu'awiyah came to Al-Madinah and addressed us. He took hold of a hairpiece and said: 'I never used to see anyone do this except the Jews. The Messenger of Allah [SAW] heard of it and he called it "giving a false impression."

"O people, the Prophet [SAW] forbade you to give false impressions. He brought a piece of black cloth and threw it in front of them and said: 'This is what women are putting on their heads and covering it.'"

The Messenger of Allah [SAW] forbade giving a false impression, and the false impression of a woman when she adds extra hair to her head.

The Messenger of Allah [SAW] cursed the woman who affixes hair extensions.

A woman came to the Messenger of Allah [SAW] and said: "O Messenger of Allah [SAW], a daughter of mine is going to get married. She got sick and her hair fell out. Is there any sin on me if I give her hair extensions?" He said: "Allah has cursed the woman who affixes hair extensions and the one who has that done."

"The Messenger of Allah [SAW] cursed the woman who affixes hair extensions and the one who has that done, and the woman who does tattoos and the one who has that done."

"May Allah curse Al-Mutanammisat and who have their teeth separated. Shall I not curse those whom the Messenger of Allah [SAW] cursed?"

"The Messenger of Allah [SAW] cursed the women who do tattoos, those who have their teeth separated and Al-Mutanammisat who change the creation of Allah, the Mighty and Sublime."

"May Allah curse Al-Mutanammisat and their teeth separated, who have tattoos done, changing the creation of Allah." A woman came to him and said: "Are you the one who said such-and-such?" He said: "Why should I not say what the Messenger of Allah [SAW] said?"

"Abdullah used to say: 'May Allah curse the women who have tattoos done and Al-Mutanammisat, and have the women who have their teeth separated. Should I not curse those whom the Messenger of Allah [SAW] cursed?'"

"The Messenger of Allah [SAW] forbade men to use saffron."

"The Messenger of Allah (ﷺ) forbade men to use saffron on their skin."

"If perfume was brought to the Prophet [SAW], he would not refuse it."
