He who truly remembers Allah is the one who obeys Him: whoever forgets is disobedient. Obedience is the mark of guidance, disobedience the sign of misguidance. The root of both states lies in remembrance (dhikr) and forgetfulness. Make your heart the focal point of your tongue, which should not move unless the heart indicates, the intellect agrees and your tongue accords with belief. Almighty Allah knows what you conceal and what you reveal.
