Mambo Ya Walawi 27:19

Kama mtu anayeweka wakfu shamba anataka kulikomboa, lazima aongeze sehemu ya tano ya thamani yake, nalo shamba litakuwa lake tena.

And if he that sanctified the field will in any wise redeem it, then he shall add the fifth part of the money of thy estimation unto it, and it shall be assured to him.
