Al-Baqarah - 2:223

نِسَآؤُكُمْ حَرْثٌ لَّكُمْ فَأْتُواْ حَرْثَكُمْ أَنَّى شِئْتُمْ وَقَدِّمُواْ لأَنفُسِكُمْ وَاتَّقُواْ اللّهَ وَاعْلَمُواْ أَنَّكُم مُّلاَقُوهُ وَبَشِّرِ الْمُؤْمِنِينَ
[2:223]
Your wives are a tilth for you, so go into your tilth when you like, and do good beforehand for yourselves, and be careful (of your duty) to Allah, and know that you will meet Him, and give good news to the believers.
Your wives are as a tilth unto you; so approach your tilth when or how ye will; but do some good act for your souls beforehand; and fear Allah. And know that ye are to meet Him (in the Hereafter), and give (these) good tidings to those who believe.
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).
