(1) Shaykh al-Islam Ibn Taymiyya writes in al-Safadiyya, 2:318: “For this reason, the Prophet had with many of the idolaters both open-ended and time-limited treaties; the latter were binding, whereas the former were not—either party could revoke them.” He goes on: “Some jurists imagined that it is impermissible to conclude a pact with the unbelievers except for a fixed term … The correct view is that a pact may be made either open-ended or time-limited. If it is time-limited, it is binding … but if it is open-ended, it is not binding, because binding contracts are never perpetual, just like a partnership or an agency.” See also: al-Jawab al-Sahih, 1:176; Majmuʿ al-Fatawa, 29:145.
