The Women
يَسْتَخْفُونَ مِنَ ٱلنَّاسِ وَلَا يَسْتَخْفُونَ مِنَ ٱللَّهِ وَهُوَ مَعَهُمْ إِذْ يُبَيِّتُونَ مَا لَا يَرْضَىٰ مِنَ ٱلْقَوْلِ ۚ وَكَانَ ٱللَّهُ بِمَا يَعْمَلُونَ 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.

وَٱسْتَغْفِرِ ٱللَّهَ ۖ إِنَّ ٱللَّهَ كَانَ غَفُورًا رَّحِيمًا
And seek forgiveness of Allah. Indeed, Allah is ever Forgiving and Merciful.
وَلَا تُجَـٰدِلْ عَنِ ٱلَّذِينَ يَخْتَانُونَ أَنفُسَهُمْ ۚ إِنَّ ٱللَّهَ لَا يُحِبُّ مَن كَانَ خَوَّانًا أَثِيمًا
And do not argue on behalf of those who deceive themselves. Indeed, Allah loves not one who is a habitually sinful deceiver.
هَـٰٓأَنتُمْ هَـٰٓؤُلَآءِ جَـٰدَلْتُمْ عَنْهُمْ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا فَمَن يُجَـٰدِلُ ٱللَّهَ عَنْهُمْ يَوْمَ ٱلْقِيَـٰمَةِ أَم مَّن يَكُونُ عَلَيْهِمْ وَكِيلًا
Here you are - those who argue on their behalf in [this] worldly life - but who will argue with Allah for them on the Day of Resurrection, or who will [then] be their representative?
وَمَن يَعْمَلْ سُوٓءًا أَوْ يَظْلِمْ نَفْسَهُۥ ثُمَّ يَسْتَغْفِرِ ٱللَّهَ يَجِدِ ٱللَّهَ غَفُورًا رَّحِيمًا
And whoever does a wrong or wrongs himself but then seeks forgiveness of Allah will find Allah Forgiving and Merciful.
