Is the 'Umrah valid if I cut some of my hair?

The Shaykh : What is the number of this question?

The questioner : This is probably the fourth one.

The Shaykh : Yes, bring the fifth one.

The questioner : Before I leave, if one of these boys went and played with his head, as you mentioned, and they cut some of his hair, is his 'Umrah valid?

The Shaykh : What is valid?
The student : His 'Umrah.

The questioner : I say, usually people stand at the gate of the Haram with a group of Yemenis who have scissors, just to get a riyal. They might cut two hairs for him. Some people, so that they... don't cut it. We say this person's 'Umrah is valid, or what does it mean? What do we say about it?

The Shaykh : We say it is deficient, without a doubt, except in one case.

The questioner: Yes.

The Shaykh : If these people were influenced by some ignorant scholars who are thought to be good and are considered people of knowledge, and they told him that a few hairs are sufficient, as these young boys do.

The questioner: Yes.

The Shaykh : In that case, the sin is on the one who issued the ruling to them.

The questioner : Yes, that is fine.
