نِسَآؤُكُمْ حَرْثٌۭ لَّكُمْ فَأْتُوا۟ حَرْثَكُمْ أَنَّىٰ شِئْتُمْ ۖ وَقَدِّمُوا۟ لِأَنفُسِكُمْ ۚ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّكُم مُّلَٰقُوهُ ۗ وَبَشِّرِ ٱلْمُؤْمِنِينَ
Your women are a tilth for you (to cultivate) so go to your tilth as ye will, and send (good deeds) before you for your souls, and fear Allah, and know that ye will (one day) meet Him. Give glad tidings to believers, (O Muhammad).
