O ye who believe! seek help with patient perseverance and prayer; for Allah is with those who patiently persevere.
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱسْتَعِينُوا۟ بِٱلصَّبْرِ وَٱلصَّلَوٰةِ ۚ إِنَّ ٱللَّهَ مَعَ ٱلصَّـٰبِرِينَ
Quran 2:153
The same idea in other traditions
The Master said, "Specious words confound virtue. Want of forbearance in small matters confounds great plans."
A man is not learned because he talks much; he who is patient, free from hatred and fear, he is called learned.
Better is the end of a thing than the beginning thereof; And the patient in spirit is better than the proud in spirit.
By conquering anger he obtains patience; he acquires no Karman productive of anger, and destroys the Karman he had acquired before.
Give me the cup! a voice rings in mine ears / Crying: “Bear patiently the bitter years! / For all thine ills, I send thee heavenly grace. …
And not only so, but we glory in tribulations also: knowing that tribulation worketh patience; And patience, experience; and experience, hope:
Let patience be your purpose in life; implant this within your being. In this way, you will grow into a great river; you will not break off into a tiny stream.
