Ista-aaza is one of the important one of the important aspects of the faith and is obligatory on every Muslim. As already been mentioned, earlier, it should be from the depths of the heart of the person and not just the repetition of the words through the mouth. Quran wants people to
---fa astaiz billah--- seek Allah's protection. This means that the words should not be repeated as a force of habit like the parrots. The reality requires one to seek freedom from the accursed Satan and submit to Allah for His help. If these two objectives are achieved, then the Ista-aaza is really Ista-aaza! Otherwise it will just be an exercise in futility. In a nutshell, when the words of the Ista-aaza are uttered, it should be in the true spirit required of him.

When we consider carefully the spirit of Ista-aaza, we find that it has five well-defined aspects: 1.Taqwa or piety.2.Tadakkar or remembrance of Allah. 3. Tawakkal or trust in Allah. 4. Iqlas or sincerity. 5. Aajizi or humility towards Allah.

When all these four aspects are practiced by a person, his Ista-aaza will be accepted by Allah. Then the accursed Satan will remain a long distance away from the person whether he says aaoozu billahi min al Shaitan ir rajeem or not. In other words, when Satan comes to a momin he becomes scared of man as an ordinary human being gets scared of the company of Jinns.
