It is narrated from Ibn Aun who says that Muhammad disliked cutting the crow of the throat, and in my opinion, there was no religious reason for his dislike.

It is narrated from Hazrat Abdullah bin Utbah, he says that our wet nurse brought her child to Hazrat Abdullah bin Mas'ud (may Allah be pleased with him), whose uvula had fallen down, and those people intended to cut the fallen uvula. Hazrat Abdullah bin Mas'ud (may Allah be pleased with him) said: Do not cut it. Yes, if his death is delayed, he will recover; otherwise, if you cut it, it will not be so.
