اللَّهُمَّ لَا سَهْلَ إِلَّا مَا جَعَلْتَهُ سَهْلاً، وَأَنْتَ تَجْعَلُ الْحَزْنَ إِذا شِئْتَ سَهْلاً
O Allāh, there is no ease except in that which You have made easy, and You make the difficulty, if You wish, easy.
Reference: O Allāh, there is no ease except in that which You have made easy, and You make the difficulty, if You wish, easy. Ibn Ḥibbān in his _Ṣaḥīḥ_ (#2427), Mawārid and Ibn al-Sunnī (#351). Ibn Ḥajar said: “This ḥadīth is ṣaḥīḥ.” ʿAbd al-Qādir al-Arnaʾūṭ also declared it ṣaḥīḥ in his takrīj of Imām al-Nawawī's _al-Athkār_ (p.\ 106).
