The Prophet ﷺ said: When one of you asked a woman in marriage, if he is able to look at what will induce him to marry her, he should do so. He (Jabir) said: I asked a girl in marriage, I used to look at her secretly, until I looked at what induced me to marry her. I, therefore, married her. (Using translation from Abū Dāʾūd 2082)
قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا خَطَبَ أَحَدُكُمُ امْرَأَةً فَإِنِ اسْتَطَاعَ أَنْ يَنْظُرَ إِلَى بَعْضِ مَا يَدْعُوهُ إِلَى نِكَاحِهَا فَلْيَفْعَلْ» فَخَطَبْتُ امْرَأَةً مِنْ بَنِي سُلَيْمٍ فَكُنْتُ أَتَخَبَّأُ لَهَا فِي أُصُولِ النَّخْلِ حَتَّى رَأَيْتُ مِنْهَا مَا دَعَانِي إِلَى نِكَاحِهَا فَتَزَوَّجْتُهَا
