Hisham Ibn Muhammad informed us; he said: Jamil Ibn Marthad
related to me; he said:
A member of the Ajiyin whose name was Habib Ibn ‘Amr, waited on the
Prophet, may Allah bless him. So he wrote an epistle for him: This is an
epistle from Muhammad, the Apostle of Allah, to Habib Ibn ‘Amr, the
brother of Banu Aja and to him from among his people who embrace
Islam, offer prayers, pay zakah from what he possesses and his water
well; and there will be no (further tax) on his urban or rura! (property).
For this, there is the guarantee of Allah and the guarantee of His Apostle.
