In page Shah Jahan:

"

Shah Jahan sent an embassy to the Ottoman court in 1637. Led by Mir Zarif, it reached Sultan Murad IV the following year, while he was encamped in Baghdad. Zarif presented him with fine gifts and a letter that encouraged an alliance against Safavid Persia. The Sultan sent a return embassy led by Arsalan Agha. Shah Jahan received the ambassador in June 1640.[citation needed]
