quran:29:2 –

Do the people think that they will be left to say, "We believe" and they will not be tried?  

Do people suppose that they will be left to say, that is, ˹that they will be left alone˺ because of their saying, ‘We believe’, and they will not be tried?, tested with that which will reveal the sincerity of their belief. This ˹verse˺ was revealed regarding a group of individuals who when they became believers endured suffering at the hands of the idolaters.
القرآن:٢٩:٢ –

أَحَسِبَ النَّاسُ أَنْ يُتْرَكُوا أَنْ يَقُولُوا آمَنَّا وَهُمْ لَا يُفْتَنُونَ  

{أحسب الناس أن يتركوا أن يقولوا} أي: بقولهم {آمنا وهم لا يفتنون} يختبرون بما يتبين به حقيقة إيمانهم، نزل في جماعة آمنوا فآذاهم المشركون.
