It was narrated from Masrooq that

A woman came to Ibn Mas'ood and said: I have been told that you forbid hair extensions? He said: Yes. She said: Is it something that you find in the Book of Allah or that you heard from The Messenger of Allah (ﷺ)? He said: I find it in the Book of Allah and from The Messenger of Allah (ﷺ). She said: By Allah, I have read what is between the covers of the Mushaf and I did not find in it what you are saying. He said: Did you find in it (the words), "And whatsoever the Messenger (Muhammad (ﷺ)) gives you, take it; and whatsoever he forbids you, abstain (from it)" (al-Hashr 59:7)? She said: Yes. He said: Then I heard the Messenger of Allah (ﷺ) forbid plucking facial hair, filing teeth, adding hair extensions and tattooing except in the case of disease. The woman said: Perhaps some of your womenfolk do that? He said: Go inside (and see). She went inside, then she came out and said: I did not see anything wrong. He said: (If it were otherwise) I would not have paid heed to the recommendation of the righteous slave of Allah, "I wish not, in contradiction to you, to do that which I forbid you" (Hood 11:88).
