Under the year 867/1462, 'Abd al-Razzāq describes Jihān-shāh's rule in the following terms, ibid., 1271: ' Owing to the benevolent administration (ḥusn-i 'ināyat va luṭf-i 'āṭifat) of Mirza Jihān-shāh, Azarbayjan was a highly thriving state. That well-meaning sovereign was anxious to practise justice, to secure the prosperity of the country, and to treat his subjects honourably. The capital, Tabriz, by its numerous population and the prevalence of tranquillity, emulated Egypt (miṣr-i jāmi'). The rumours of the good behaviour of that felicitous king spread throughout the world. The inhabitants of his God-protected kingdom, indifferent to the arrows of events, enjoyed peace '.
