Question :
While in state of ablution, I cut my nails. Should I renew my ablution or will washing hands suffice?
The Answer :
All perfect praise be to Allah, The Lord of the Worlds, and may His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
In your case, you aren’t required to renew Wudu (Ablution) nor wash hands, whether you cut your nails before or after having performed ablution, and the same applies to cutting hair so long as you wiped your head while performing ablution. In addition, what you`ve mentioned isn`t amongst the nullifiers of Wudu`. And Allah Knows Best.
