O Allah, this is the coming of Your night and the departing of Your day, and these are the voices of those who call upon You, so forgive me. O Allah, You know that these hearts have gathered upon loving You, have met upon obeying You, have united upon calling to Your path, and have pledged to support Your law. O Allah, strengthen their bond, make their love endure, guide them on their paths, and fill them with Your light that never fades. Open their hearts with an abundance of faith in You and the beauty of reliance upon You. Give them life through knowledge of You, and let them die as martyrs in Your cause. Indeed, You are the Best Protector and the Best Helper. And may Allah's blessings be upon our master Muhammad, and upon his family and companions. Amin. And all praise is due to Allah, Lord of the worlds.
