Or think you that you will enter Paradise without such (trials) as came to those who passed away before you? They were afflicted with severe poverty and ailments and were so shaken that even the Messenger and those who believed along with him said, ‘When (will come) the Help of Allah?’ Yes! Certainly, the Help of Allah is near! Quran 2:214
Alif-Lam-Mim. Do people think that they will be left alone because they say: ‘We believe’, and will not be tested. And We indeed tested those who were before them. And Allah will certainly make known those who are true, and and will certainly make known those who are liars.
– Quran 29:1-3
