اللَّهُمَّ لَا سَهْلَ إِلَّا مَا جَعَلْتَهُ سَهْلًا، وَأَنْتَ تَجْعَلُ الْحَزْنَ إِذَا شِئْتَ سَهْلًا
Transliteration
Allahumma la sahla illa ma ja'altahu sahla, wa anta taj'alul-hazna idha shi'ta sahla
Translation
O Allah, there is no ease except what You make easy, and You make difficulty easy if You will.
