Du'aa' has a very strong relationship with one's 'aqeedah (creed) [عقيدة, plural: 'aqaa'id عقائد] and tawḥeed [توحيد]. Du'aa' is also one of the best ways that a person can increase his eemaan (faith) [ايمان] , and appreciate Allaah's Names and Attributes. It is a powerful reminder of man's inherent incapability, and Allaah's unlimited powers. Du'aa' increases a person's eemaan due to many factors. It makes evident the fact that a person has absolutely no control over his destiny, nor does he have the power to benefit himself or avert any evil from him. It shows the neediness that a Muslim feels towards his Lord. It proves that the one making du'aa' sincerely believes that Allaah سبحانه و تعالى hears his du'aa', and will respond to it. Such a person must also affirm Allaah's Infinite Mercy, Beneficence and Generosity. And the more a person increases in the realisation of his poverty towards the Mercy of his Lord, the more he will increase in his eemaan as well. Likewise, the more a person appreciates and realises the perfection of Allaah's Names and Attributes, so too will he increase in his eemaan. These two factors - knowing one's need of Allaah سبحانه و تعالى in every matter, and knowing Allaah's Perfect Nature - are the essence of eemaan and servitude to Allaah سبحانه و تعالى. The one making du'aa' openly affirms his eemaan for Allaah سبحانه و تعالى, for it shows that he believes in Allaah سبحانه و تعالى, and that Allaah, and only Allaah, can listen and answer his prayers.
