27 – Book of Reviving Dead Land (Iḥyāʾ al-Mawāt)
Dead land (mawāt) is ground from which no benefit is presently derived because its water supply has ceased, or because it is submerged, or for any similar reason that prevents cultivation. Any such tract that is wild and has no owner, or that was once owned within Islam but whose specific owner is unknown, and that lies so far from the settled area that were a person to stand at the farthest edge of the habitation and shout his voice would not be heard there, is deemed mawāt.
Whoever revives this land with the permission of the ruler (imam) becomes its owner. If he revives it without permission, he does not own it according to Abū Ḥanīfa, whereas Abū Yūsuf and Muḥammad hold that he does.
A dhimmi (non-Muslim subject) acquires ownership through revival just as a Muslim does.
If someone marks off (ḥajjara) a parcel of land but fails to develop it for three years, the imam repossesses it and grants it to another.
It is not permissible to revive land that lies near inhabited property; pasture must be left for the villagers and a place where they may dump the remains of their harvest.
Whoever digs a well in the open wilderness is entitled to a protective zone (ḥarīm) around it: for an animal-watering well the ḥarīm is 40 cubits, for a drawn-water well 60 cubits, and for a natural spring 300 cubits. Anyone who wishes to dig within that ḥarīm is prevented from doing so.
When the Euphrates or the Tigris abandons a tract of riverbed and shifts course, if there remains a possibility that the river will return, the land may not be revived. If it is certain that it will not return, the land is treated like mawāt—provided it is not within the ḥarīm of an inhabited area—and, according to the Imam (Abū Ḥanīfa), whoever revives it with the ruler’s permission becomes its owner.
If a person owns a canal that traverses another man’s land, he has no right to a ḥarīm around it, according to Abū Ḥanīfa, unless he can produce evidence to that effect. Abū Yūsuf and Muḥammad, however, maintain that he is entitled to a raised embankment on which he may walk and onto which he may deposit the canal’s silt.
