اقرأ وتدبر الآية 434 من سورة سُورَةُ آلِ عِمۡرَانَ: وَلِيُمَحِّصَ اللَّهُ الَّذِينَ آمَنُوا وَيَمْحَقَ الْكَافِرِينَ
وَلِيُمَحِّصَ اللَّهُ الَّذِينَ آمَنُوا وَيَمْحَقَ الْكَافِرِينَ
and that God might render pure of all dross those who have attained to faith, and bring to nought those who deny the truth.
