This should be done with faith and trust in Allah, desiring what is with Him, and believing that He is the Disposer of affairs and the Controller of all things, capable of everything. This should not be done with doubt or ill thoughts, but with good thoughts about Allah and trust in Him. If the desired outcome is not achieved, it may be due to one of the mentioned reasons or others. The servant must take the necessary means, and Allah is the Cause of causes and the All-Wise, All-Knowing.
