In مِنَ الدُّعَاءِ, مِنْ links the object of comparison. The wording marks the honor of supplication; it does not imply that a person can compel outcomes simply by asking. Prayer is a request made to Allah, with results entrusted to His knowledge and wisdom.
Example 1: A student prays for success while also studying with discipline.
Example 2: Someone who is ill prays for healing while seeking suitable treatment and taking precautions.
Words of prayer, humility of heart, and responsible actions complement one another.
