It is narrated from Hazrat Anas (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) had his head shaved, he presented the right side of his head first to the barber, who cut the hair from that side. The Prophet (peace and blessings be upon him) gave those hairs to Hazrat Abu Talha (may Allah be pleased with him). Then he had the hair on the left side shaved and gave those hairs to the general people.
