وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، أَنَّهُ كَانَ يَقُولُ فِي قَوْلِ اللَّهِ تَبَارَكَ وَتَعَالَى ‏{‏وَلاَ جُنَاحَ عَلَيْكُمْ فِيمَا عَرَّضْتُمْ بِهِ مِنْ خِطْبَةِ النِّسَاءِ أَوْ أَكْنَنْتُمْ فِي أَنْفُسِكُمْ عَلِمَ اللَّهُ أَنَّكُمْ سَتَذْكُرُونَهُنَّ وَلَكِنْ لاَ تُوَاعِدُوهُنَّ سِرًّا إِلاَّ أَنْ تَقُولُوا قَوْلاً مَعْرُوفًا‏}‏ أَنْ يَقُولَ الرَّجُلُ لِلْمَرْأَةِ وَهِيَ فِي عِدَّتِهَا مِنْ وَفَاةِ زَوْجِهَا إِنَّكِ عَلَىَّ لَكَرِيمَةٌ وَإِنِّي فِيكِ لَرَاغِبٌ وَإِنَّ اللَّهَ لَسَائِقٌ إِلَيْكِ خَيْرًا وَرِزْقًا وَنَحْوَ هَذَا مِنَ الْقَوْلِ ‏.‏

Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasimthat his father said about the word of Allah, the Blessed, theExalted, "There is no fault in you about the proposal you offer towomen, or hide in yourselves. Allah knows that you will be mindful ofthem; but do not make troth with them secretly without honourablewords," (Sura 2 ayat 235) that it referred to a man saying to a womanwhile she was still in her idda after the death of her husband, "Youare dear to me, and I desire you, and Allah brings provision andblessing to you," and words such as these.
