Allah the Exalted has said: (And seek help in patience and in prayer. Surely that is something quite difficult on (people) other than people of humility and submissivness.) Surah Al-Baqarah (2):45

And He (swa) said: (Oh you who believe! Seek help in patience and in prayer. Verily, Allah is with those who are patient.) Surah Al-Baqarah (2):153

And He, the Exalted one, has said: (And command your family to pray, and be patient upon that. We are not asking you for any provisions, (rather) We provide for you, and the favorable outcome is for (those with) taqwaa (consciousness of Allah that produces righteous actions.) Surah Taa-Haa (20):132
