Al-Azkar – Hisn Al-Muslim represents a fortification for the Muslim which helps strengthening his relation with Allah and guards him against the whisperings of Satan and conditions of soul.
The Prophet (peace be upon him) used to observe supplication when going in or out the house while moving or setting and in all his actions.
The supplications include the acts concerning both this life and the hereafter. That is there are supplications for every single act of work or worship to the extent that supplications fill the Muslim’s life and surround it like a fortification.
Due to the urgent need of Muslims who adhere to the Prophetic Sunnah for supplications
