وَٱسۡتَعِينُواْ بِٱلصَّبۡرِ وَٱلصَّلَوٰةِۚ وَإِنَّهَا لَكَبِيرَةٌ إِلَّا عَلَى ٱلۡخَٰشِعِينَ
English translation: And seek help through patience and the prayer and indeed it (is) surely difficult except on the humble ones
Transliteration: wa-is'ta'inu bil-sabri wal-salati wa-innaha lakabiratun illa ala al-khashi'ina
