Assalamou aleikoum wa rahmatoullah wa barakatou
Fortification of the Muslim through remembrance and supplicaion from Quran and the Sunnah
The one I have in my bookshelf is a Darussalam publication. (on the pic of this one, it is not darussalam, but I would advise to buy only those from Darussalam)
Fortification of the Muslim through remembrance and supplicaion from Quran and the Sunnah. With 132 invocations.
Compiled and referenced by Sa'eed Ibn Ali Ibn Wahf Al Qahtaani N.b.
It is the same as Fortress of the Muslim, but I prefer the Fortress as we have the transliteration of the invocations to help us to say them in arabic. In this booklet, there is only the arabic and english. It is good for those who read arabic fluently. They do not need the transliteration.
