It is narrated from Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) that he said: "We performed an Umrah with the Messenger of Allah (peace and blessings be upon him), in which he (peace and blessings be upon him) had his hair shaved, so I hastened and obtained the hair of his (peace and blessings be upon him) forelock. Then I took a cap and sewed that hair into the front part of the cap. After that, in whatever battle or direction I was sent, the way to victory and success was opened for me by the help of Allah."
Takhrij: Imam Ahmad bin Hanbal narrated this hadith in his Musnad (16828); Imam al-Hakim declared it sahih in al-Mustadrak (3/299) and Imam al-Dhahabi agreed with him, while Allamah al-Haythami stated in Majma' al-Zawa'id that its chain consists of thiqat (trustworthy) narrators.
