Wakf property can only be sold with the permission of the Board

In Rajasthan Wakf Board Vs. Devki Nandan Pathak, the Supreme Court held that Once the property is declared to be a Wakf property, a fortiori, whether the sale of such property is made by a person not connected with the affairs of the Wakf or by a person dealing with the affairs of the Wakf, the same becomes void by virtue of Section 51 of the Act unless it is proved that it was made after obtaining prior permission of the Board as provided under the Act.
