Ruling on removing hair for one who intends to perform 'Umrah and Hajj while intending to offer a sacrifice

Question: I had intended to perform Hajj as a mutamatti', but when I arrived in Ta'if, I changed my mind and entered the state of ihram for Hajj alone. If I want to offer a sacrifice on the day of 'Id, is that permissible? I should mention that I shortened my hair on the fourth of Dhu al-Hijjah. I ask Allah to reward you with good for us.

Answer: If a pilgrim or anyone else intends to offer a sacrifice, even if he has already shaved his head, shortened his hair, or trimmed his nails, there is no blame on him for that. However, if he resolves to offer a sacrifice after the month of Dhu al-Hijjah has begun, he must refrain from taking anything from his hair, nails, or skin until he offers the sacrifice. This is based on the saying of the Prophet (peace and blessings be upon him): narrated by Imam Muslim in his Sahih.
As for his entering the state of ihram for Hajj alone, having intended to enter ihram for 'Umrah, and then deciding after reaching the miqat to enter ihram for Hajj, there is no blame in that. However, combining 'Umrah with Hajj (tamattu') is better if his arrival is during the months of Hajj. But if his arrival in Makkah is before the month of Shawwal begins, what is prescribed for him is to enter ihram for 'Umrah only.
