Is there a risk to giving pan to tenant

I am landlord but wary of sharing pan number with tenant. Tenant needs it for his hra provisions. I have heard few cases where tenants have misused landlord pan to inflate rent paid and claim higher deductions, since landlord has no way of seeing what tenant is putting in his ITR. This puts landlord at risk of additional demand from income tax dept due to higher than actual rent claimed by tenant How do I circumvent this problem, how can I avoid sharing my pan number.
