Question Detail:

WHAT ABOUT CUTTING OF NAILS AND HAIR AFTER SEEING THE MOON OF zILHAJ?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
The Fuqahaa (Jurists) have mentioned that it is Mustahab for one doing Qurbani to abstain from cutting one’s nails and hair during the first ten days of Dhul-Hijjah.
However, if one has not cut one’s hair for forty days or more, one should cut one’s hair irrespective of the above.[1]
Furthermore, if one’s nails are so long that it may injure one, one may cut one’s nails.[2]
And Allah Ta’āla Knows Best
