Quran verse about Trials

أعوذ بالله من الشيطان الرجيم 

Al-Furqan 25:20

وَمَآ أَرْسَلْنَا قَبْلَكَ مِنَ ٱلْمُرْسَلِينَ إِلَّآ إِنَّهُمْ لَيَأْكُلُونَ ٱلطَّعَامَ وَيَمْشُونَ فِى ٱلْأَسْوَاقِۗ وَجَعَلْنَا بَعْضَكُمْ لِبَعْضٍ فِتْنَةً أَتَصْبِرُونَۗ وَكَانَ رَبُّكَ بَصِيرًا 

And We did not send before you, [O Muhammad], any of the messengers except that they ate food and walked in the markets. And We have made some of you [people] as trial for others -  will you have patience? And ever is your Lord, Seeing.
