وَلَا جُنَاحَ عَلَيْكُمْ فِيمَا عَرَّضْتُم بِهِ مِنْ خِطْبَةِ النِّسَاءِ أَوْ أَكْنَنتُمْ فِي أَنفُسِكُمْ عَلِمَ اللَّهُ أَنَّكُمْ سَتَذْكُرُونَهُنَّ وَلَكِن لَّا تُوَاعِدُوهُنَّ سِرًّا إِلَّا أَن تَقُولُوا قَوْلًا مَّعْرُوفًا وَلَا تَعْزِمُوا عُقْدَةَ النِّكَاحِ حَتَّى يَبْلُغَ الْكِتَابُ أَجَلَهُ وَاعْلَمُوا أَنَّ اللَّهَ يَعْلَمُ مَا فِي أَنفُسِكُمْ فَاحْذَرُوهُ وَاعْلَمُوا أَنَّ اللَّهَ غَفُورٌ حَلِيمٌ
There is no sin upon you in what you may hint in proposing to [recently widowed] women, or what you may secretly cherish within your hearts. Allah knows that you will be thinking of them, but do not make troth with them secretly, unless you say honourable words, and do not resolve on a marriage tie until the prescribed term is complete. Know that Allah knows what is in your hearts, so beware of Him; and know that Allah is all-forgiving, all-forbearing.
Agha Ali Puya Commentary
Commentary on Quran 2:235
[Pooya/Ali Commentary 2:235] There is no harm if some one desires to marry a widow who is keeping herself in waiting for the prescribed period (iddat), and indirectly speaks his mind, but there should be no confirmation of the marriage tie until the period of waiting is completed.
