In the Name of Allah, Most Gracious, Most Merciful.
Allah has guaranteed the response of the dua of the one in distress, as He Himself has informed us of this guarantee. And the reason for this is that the one in distress will turn to Him in pure sincerity, cutting his hope off from all other sources. And sincerity to Him is the cause of gaining His protection, regardless of whether it comes from a Muslim, non-Muslim, evil or pious.
