A gift; a benefaction in general. A gift by a superior to an inferior. In India, the term is especially applied to grants of land held rent-free, and in hereditary and perpetual occupation; the tenure came in time to be qualified by the reservation of a portion of the assessable revenue, or by the exaction of all proceeds exceeding the intended value of the original assignment; the term also vaguely applied to grants of rent-free land without reference to perpetuity or any specified conditions. The grants are also distinguished by their origin from the ruling authorities, or from the village communities, and are again distinguishable by peculiar reservations, or by their being applicable to different objects.
Sanad-i-In’am is a grant emanating from the ruling power of the time of the grant, free from all Government exactions, in perpetuity, and validified by a Sanad, or official deed of grant; it usually comprises land included in the village area, but which is uncultivated, or has been abandoned; and it is subject to the village functionaries.
Nisbat-i-In’am (from nisbah, “a portion”), are lands granted rent-free by the village out of its own lands; the loss or deduction thence accruing to the Government, assessment being made good by the village community. (Wilson’s Glossary of Indian Terms.)
