ثُمَّ أَنزَلَ عَلَيكُم مِن بَعدِ الغَمِّ أَمَنَةً نُعاسًا يَغشىٰ طائِفَةً مِنكُم ۖ وَطائِفَةٌ قَد أَهَمَّتهُم أَنفُسُهُم يَظُنّونَ بِاللَّهِ غَيرَ الحَقِّ ظَنَّ الجاهِلِيَّةِ ۖ يَقولونَ هَل لَنا مِنَ الأَمرِ مِن شَيءٍ ۗ قُل إِنَّ الأَمرَ كُلَّهُ لِلَّهِ ۗ يُخفونَ في أَنفُسِهِم ما لا يُبدونَ لَكَ ۖ يَقولونَ لَو كانَ لَنا مِنَ الأَمرِ شَيءٌ ما قُتِلنا هاهُنا ۗ قُل لَو كُنتُم في بُيوتِكُم لَبَرَزَ الَّذينَ كُتِبَ عَلَيهِمُ القَتلُ إِلىٰ مَضاجِعِهِم ۖ وَلِيَبتَلِيَ اللَّهُ ما في صُدورِكُم وَلِيُمَحِّصَ ما في قُلوبِكُم ۗ وَاللَّهُ عَليمٌ بِذاتِ الصُّدورِ

After the setback, He sent down tranquility upon you. A slumber overcame some of you, while others were concerned only about themselves, harboring misconceptions about God—thoughts of ignorance. They asked, “Do we have any say in the matter?” Say, “The entire affair rests with God.” They conceal within themselves what they don’t disclose to you. They say, “If we had control over the situation, we wouldn’t have been killed here.” Say, “Even if you had been inside your homes, those destined to be killed would have met their end.” Thus, God tests your inner selves and purifies your hearts. God is aware of the innermost thoughts.
