Takhrij Hadith 1824: "He saw Khalid ibn al-Walid…"

He saw Khalid ibn al-Walid (may Allah be pleased with him) while the Messenger of Allah (peace and blessings be upon him) was shaving his head. Khalid said: "O Messenger of Allah, your forelock! Do not let anyone else have preference over me for it — may my father and mother be sacrificed for you!". So he took the forelock of the Messenger of Allah (peace and blessings be upon him) and would place it upon his eyes and in his mouth.
