On one occasion, Muhammad Nasawi was sent as an envoy of Jalaluddin to Alamut to demand the balance of the tribute that was owing for Damghan, and to settle other points of dispute. He succeeded to have his nice meetings with Alauddin Muhammad and his vizir Imaduddin at Alamut.
Nasawi described his mission with satisfaction in his "Sirat-i Jalaluddin" (pp. 232-3) that, "Alauddin Muhammad favoured me above all the other envoys of the sultan, treating me with great respect and beauty. He dealt generously with me, and gave me twice the usual amount in gifts and robes of honour. This is an honourable man. Generosity to such a man is never wasted. The value of what was bestowed on me, in cash and in kind, was near 3000 dinars, including two robes of honour, each consisting of a satin cloak, a hood, a fur and a cape, one lined with satin and the other with Chinese crepe; two belts of 200 dinars weight; 70 pieces of cloth; two horses with saddles, bridles and harness and pommels; a thousand dinars in gold; four caparisoned horses; a string of Bactrian camels; and thirty robes of honour for my suite."
From the narratives of Muhammad Nasawi, it appears that he obtained only a compromise solution during his meetings, He however, describes his mission with extreme satisfaction.
The Ismailis acquired new regions in Gilan and entered Ruyan. The Baduspanid ruler, Fakhr ad-Dawla Namavar bin Bisutun, who had succeeded his father shortly before 620/1223 was obliged to leave Ruyan. On the other hand, the relation between the Rudhbari Ismailis and the Qazwinis had finally become peaceful.
According to "Jamiut Tawarikh" (p. 181), Alauddin Muhammad procured a close association with a Sufi Shaikh of Qazwin, Jamaluddin Gili (d. 651/1253) and sent him an annual grant of 500 gold dinars; who according to "Dabistan al-Mazahib" (1st vol., p. 265), had privily espoused Ismailism. The attitude of the Muslims of Qazwin in this context became more aggressive, therefore, Alauddin Muhammad had to warn them that, "If the abode of Shaikh Jamaluddin was not in Qazwin, I would have not spared even the dust of your town."
