for stranded travellers. Into this last share fall the poor among the Prophet’s kin, and they are given precedence, whereas nothing is handed to those of them who are wealthy.
The opening words of the verse on the khums—“for Allah…”—serve only as an introductory blessing by invoking His Name. The Prophet’s own portion—peace and blessings be upon him—expired with his death, just as his exclusive right to select a prized article (al-ṣafī) lapsed. His relatives’ share belonged to them in his lifetime on account of their support, and after him only when they are in need.
If a single fighter, or even two, slip into enemy territory on an unauthorised raid and seize something, that property is not subject to khums. Should a sizeable, self-reliant party do the same and capture booty, one-fifth must be taken from it even though the imam did not grant them leave.
When a Muslim enters the enemy land as a merchant, it is unlawful for him to touch either their property or their lives. If he betrays them, seizes something, and brings it home, he becomes its owner in an illicit sense and is ordered to give it away in charity.
If an enemy combatant comes to us under a guarantee of safety, he is not allowed to remain in our land for a full year. The imam tells him, “Should you complete the year I shall impose the jizya upon you.” If he does remain, the tax is taken, he becomes a dhimmi, and he is thereafter barred from returning to dar al-harb. Should he go back to enemy territory after leaving a deposit with a Muslim or a dhimmi, or after incurring a debt owed by them, his protection is cancelled by that return and whatever property of his is still in dar al-islam is liable to seizure. If he is captured or killed, his debts are extinguished and the deposit becomes fayʾ.
Any wealth of the enemy that Muslims acquire without actual fighting is to be spent on the communal interests of the Muslims in the same way that kharaj revenues are spent.
All land of the Arabs is tithe-land; it stretches from al-ʿAdhib to the furthest limits of Ḥijr, and, in Yemen, from Mahra up to the border.
