اللَّهُمَّ لاَ سَهْلَ إِلاَّ مَا جَعَلْتَهُ سَهْلاً، وَأَنْتَ تَجْعَلُ الْحَزْنَ إِذَا شِئْتَ سَهْلاً

Transliteration:

Allāhumma lā saḥla illā ma ja`altahu saḥla wa anta taj`alu ‘l-ḥazna idhā shi'ta saḥla.

Translation:

O Allah, there is no ease other than what You make easy. If You please You ease sorrow.
