مَنْ سَرَّهُ أَنْ يَسْتَجِيْبَ اللهُ لَهُ عِنْدَ الشَّدَائِدِ وَالْكَرْبِ فَلْيُكْثِرِ

الدُّعَاءَ فِي الْرَّخَاْءِ

From Abu Hurairah that the Prophet صلى الله عليه وسلم said, “Whoever would be delighted by Allaah responding to him in times of hardship and distress, then let him supplicate abundantly when at ease.”

And from Aaishah, may Allaah be pleased with her, that the Messenger صلى الله عليه وسلم would remember Allaah, the Most High, at all times.
