The Meaning of Satan’s Knots on the Nape of the Head

Question:
He says: A hadith was mentioned that I read, Honorable Shaykh: Are these knots physical or conceptual? And what is their meaning?

Answer:
The knots are as the Prophet (peace and blessings be upon him) informed us about them. He said: This is Satan’s purpose with these knots: to make his sleep heavy and to delay his waking, so that he misses the prayer. So when the Muslim wakes up and remembers Allah, one knot is undone; when he performs ablution, the second knot is undone; and when he prays, the third knot is undone. Then he becomes energetic and in a good mood. This is how the Messenger (peace and blessings be upon him) informed us about these knots and how they are undone. Yes.
