Hadith.2746 - Abu Basir narrated from Abu Abdullah (as): I asked him about a person performing tamattu‘ who intended to trim their hair but instead shaved their head.
Imam (as) said: "They must offer a sheep as expiation. On the Day of Sacrifice (Yawm al-Nahr), they should pass a razor over their head when they intend to shave."
