Al Baqarah Ayah 235

وَلَا جُنَاحَ عَلَيْكُمْ فِيمَا عَرَّضْتُم بِهِۦ مِنْ خِطْبَةِ ٱلنِّسَآءِ أَوْ أَكْنَنتُمْ فِىٓ أَنفُسِكُمْ‌ۚ عَلِمَ ٱللَّهُ أَنَّكُمْ سَتَذْكُرُونَهُنَّ وَلَـٰكِن لَّا تُوَاعِدُوهُنَّ سِرًّا إِلَّآ أَن تَقُولُواْ قَوْلاً مَّعْرُوفًا‌ۚ وَلَا تَعْزِمُواْ عُقْدَةَ ٱلنِّكَاحِ حَتَّىٰ يَبْلُغَ ٱلْكِتَـٰبُ أَجَلَهُۥ‌ۚ وَٱعْلَمُوٓاْ أَنَّ ٱللَّهَ يَعْلَمُ مَا فِىٓ أَنفُسِكُمْ فَٱحْذَرُوهُ‌ۚ وَٱعْلَمُوٓاْ أَنَّ ٱللَّهَ غَفُورٌ حَلِيمٌ ٢٣٥ There is no blame on you for subtly showing interest in ?divorced or widowed? women or for hiding ?the intention? in your hearts. Allah knows that you are considering them ?for marriage?. But do not make a secret commitment with them—you can only show interest in them appropriately. Do not commit to the bond of marriage until the waiting period expires. Know that Allah is aware of what is in your hearts, so beware of Him. And know that Allah is All-Forgiving, Most Forbearing.
