All praise goes to Allah, the Lord of the universe, I testify that there is no deity worthy of worship except Allah, Alone, without partner, and I testify that Muhammad is His servant and Messenger, the praises and greetings of Allah be upon him abundantly.

Next: This epistle includes a beneficial summary about the best, greatest, noblest and most beneficial saying, the saying of monotheism "There is no deity worthy of worship except Allah", its virtues, meanings, conditions and nullifiers.

Basically, this epistle is taken from my book “Fiqh al-acriyah wa al-adhkâr”; some noble brethren wanted it to be published independently, hoping that it could be used as much as possible and that it would make it easier to benefit from it. I ask Allah to magnify the blessing of this, to make it a door of guidance for whomever He wills of His servants and to guide us all to His straight path, the path of those whom Allah has bestowed with His blessings among the prophets, the truthful, the martyrs, and the righteous, and what good company theirs is. Allah is enough for us and what a good protector, and praise and salvation be upon our Prophet Muhammad and his Family and Companions.
