Ruling on trimming the moustache and the nails and removing pubic hair

Q 3: I entered into Ihram (ceremonial state for Hajj or 'Umrah) for 'Umrah (lesser pilgrimage) from Al-Madinah Al-Munawwarah. I bathed and put on Ihram (garment worn while in the ceremonial state for Hajj and 'Umrah), but I did not cut any hair or nails while in Ihram, until after Tawaf (circumambulation of the Ka'bah) and Sa`y (going between Safa and Marwah during Hajj and `Umrah); after which I clipped my nails and shaved my head. Am I required to offer expiation or not? (Part No. 10; Page No. 134

A: Trimming the moustache and the nails and removing pubic hair upon entering the state Ihram is not an obligation, but it is among the recommended acts of Ihram. So, whoever abandons it is not required to offer any expiation.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
