Peace, mercy, and blessings of Allah be upon you! Allah Almighty has blessed you with the latest victories in the north. It is a joyful moment for us to congratulate you on these victories and renew our pledge that we will stand by your side. We will join hands with you for the support of Islam, the strengthening of the Islamic government, and the raising of the word of Allah, until corruption comes to an end and the religion belongs to Allah. On this occasion, we also reaffirm our pledge that you are our legitimate Amir. Supporting and obeying you is obligatory for us in the same way that it is obligatory to obey a legitimate ruler.
