"O Allah! Give us courage to keep away from Satan, prevent ourselves from sinning and avoid committing crimes". This Ista-aaza with Allah keeps us away from sins and reins our tongues from abusive and harmful talk. Instead of using abusive language in anger, we should rather say aaoozu billa at such times of provocation! It is always advisable to seek Allah's protection and help against the machinations of Satan. In other words, the meaning of aa oozu billa is:

aa oozu be taa-at illah min taa-at il shaitan

I seek to come in the protection of Allah and escape from the evil of Satan
