Remembering Allah Almighty (dhikr) is something recommended and deserves great rewards from Allah, as long as it is according to the Sunnah of the Prophet (peace and blessing be upon him) that mentioned many ‘adhkarwhich the Prophet(peace and blessing be upon him) used to say in the morning, in the evening, and during all his daily actions such as that mentioned in the book of Hesn Al-Muslim (Fortification of the Muslim).
There are many books written by many authors concerning this issue which explain different kinds of adhkar and how they are performed.
