27:49
قَالُ وا۟ تَقَاسَمُ وا۟ بِ ٱللَّهِ لَ نُبَيِّتَ نَّ هُۥ وَ أَهْلَ هُۥ ثُمَّ لَ نَقُولَ نَّ لِ وَلِيِّ هِۦ مَا شَهِدْ نَا مَهْلِكَ أَهْلِ هِۦ وَ إِنَّ ا لَ صَٰدِقُونَ
They said, "Take a mutual oath by Allah that we will kill him by night, he and his family. Then we will say to his executor, 'We did not witness the destruction of his family, and indeed, we are truthful.' "
4:108
يَسْتَخْفُ ونَ مِنَ ٱل نَّاسِ وَ لَا يَسْتَخْفُ ونَ مِنَ ٱللَّهِ وَ هُوَ مَعَ هُمْ إِذْ يُبَيِّتُ ونَ مَا لَا يَرْضَىٰ مِنَ ٱلْ قَوْلِ وَ كَانَ ٱللَّهُ بِ مَا يَعْمَلُ ونَ مُحِيطًا
They conceal [their evil intentions and deeds] from the people, but they cannot conceal [them] from Allah, and He is with them [in His knowledge] when they spend the night in such as He does not accept of speech. And ever is Allah, of what they do, encompassing.
4:81
وَ يَقُولُ ونَ طَاعَةٌ فَ إِذَا بَرَزُ وا۟ مِنْ عِندِ كَ بَيَّتَ طَآئِفَةٌ مِّنْ هُمْ غَيْرَ ٱلَّذِى تَقُولُ وَ ٱللَّهُ يَكْتُبُ مَا يُبَيِّتُ ونَ فَ أَعْرِضْ عَنْ هُمْ وَ تَوَكَّلْ عَلَى ٱللَّهِ وَ كَفَىٰ بِ ٱللَّهِ وَكِيلًا
And they say, "[We pledge] obedience." But when they leave you, a group of them spend the night determining to do other than what you say. But Allah records what they plan by night. So leave them alone and rely upon Allah. And sufficient is Allah as Disposer of affairs.
