The Cow
وَمِنَ ٱلنَّاسِ مَن يُعْجِبُكَ قَوْلُهُۥ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَيُشْهِدُ ٱللَّهَ عَلَىٰ مَا فِى قَلْبِهِۦ وَهُوَ أَلَدُّ ٱلْخِصَامِ
And of the people is he whose speech pleases you in worldly life, and he calls Allah to witness as to what is in his heart, yet he is the fiercest of opponents.

أُو۟لَـٰٓئِكَ لَهُمْ نَصِيبٌ مِّمَّا كَسَبُوا۟ ۚ وَٱللَّهُ سَرِيعُ ٱلْحِسَابِ
Those will have a share of what they have earned, and Allah is swift in account.
۞ وَٱذْكُرُوا۟ ٱللَّهَ فِىٓ أَيَّامٍ مَّعْدُودَٰتٍ ۚ فَمَن تَعَجَّلَ فِى يَوْمَيْنِ فَلَآ إِثْمَ عَلَيْهِ وَمَن تَأَخَّرَ فَلَآ إِثْمَ عَلَيْهِ ۚ لِمَنِ ٱتَّقَىٰ ۗ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّكُمْ إِلَيْهِ تُحْشَرُونَ
And remember Allah during [specific] numbered days. Then whoever hastens [his departure] in two days - there is no sin upon him; and whoever delays [until the third] - there is no sin upon him - for him who fears Allah. And fear Allah and know that unto Him you will be gathered.
وَإِذَا تَوَلَّىٰ سَعَىٰ فِى ٱلْأَرْضِ لِيُفْسِدَ فِيهَا وَيُهْلِكَ ٱلْحَرْثَ وَٱلنَّسْلَ ۗ وَٱللَّهُ لَا يُحِبُّ ٱلْفَسَادَ
And when he goes away, he strives throughout the land to cause corruption therein and destroy crops and animals. And Allah does not like corruption.
وَإِذَا قِيلَ لَهُ ٱتَّقِ ٱللَّهَ أَخَذَتْهُ ٱلْعِزَّةُ بِٱلْإِثْمِ ۚ فَحَسْبُهُۥ جَهَنَّمُ ۚ وَلَبِئْسَ ٱلْمِهَادُ
And when it is said to him, "Fear Allah," pride in the sin takes hold of him. Sufficient for him is Hellfire, and how wretched is the resting place.
