[4:75] – For Refuge From The Injustice Of A People Or Land And That Allah Send His Help

رَبَّنَآ أَخۡرِجۡنَا مِنۡ هَٰذِهِ ٱلۡقَرۡيَةِ ٱلظَّالِمِ أَهۡلُهَا وَٱجۡعَل لَّنَا مِن لَّدُنكَ وَلِيّٗا وَٱجۡعَل لَّنَا مِن لَّدُنكَ نَصِيرًا.

Our Lord, take us out of this city of oppressive people and appoint for us from Yourself a protector and appoint for us from Yourself a helper?

Rabbana akhrijna min hadhihi lqaryati zzalimi ahluha wajal lana min ladunka waliyyan wajal lana min ladunka naṣira

This Ayah was revealed concerning those helpless Believers who were still in Makkah before the conquest of Makkah. Allah answered their prayers and granted them someone who would undertake their affairs and defend them against the injustice of those who oppressed them. -Tafseer Al-Baghawi.
