Ahir Bhairav is a Hindustani classical raga. It is a mixture of Bhairav and the ancient but now rare raga Ahiri.
There are two approaches to this rag (Rao 1980). The first type omits Ni in the arohana: it is therefore shadav - sampurna. The second approach does not omit any note; therefore it is sampurna - sampurna. However, since no other rag shares the same modality, one need not worry too much about impinging upon a differnt rag.
