What is the ruling on an unemployed young man receiving a monthly grant from the state, if his obtaining it is conditional on submitting a fictitious work certificate from a private individual?

Entitlement to a grant depends on the condition set by the granting authority, and this condition must be adhered to. It is not permissible to resort to deception to obtain it without entitlement. Furthermore, the contractor's testimony is undeniably false and deceitful; it is a false testimony.
