Inducement to a Contract Q3

Q.
Zain is considering taking a 6-year lease of a property from a landlord named Salim. One of the lessee's covenants in the lease states that, "All external woodwork shall be painted every two years by the lessee". Qabil as an estate agent tells Zain that if he signs the lease, Salim will be satisfied if the external woodwork is painted at the end of the six years period. Zain is thus induced to sign the lease.

Discuss whether Zain is bounded by the covenant to have the external woodwork painted every two years.
