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.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا خَطَبَ أَحَدُكُمُ الْمَرْأَةَ فَإِنِ اسْتَطَاعَ أَنْ يَنْظُرَ إِلَى مَا يَدْعُوهُ إِلَى نِكَاحِهَا فَلْيَفْعَلْ قَالَ فَخَطَبْتُ جَارِيَةً فَكُنْتُ أَتَخَبَّأُ لَهَا حَتَّى رَأَيْتُ مِنْهَا مَا دَعَانِي إِلَى نِكَاحِهَا وَتَزَوُّجِهَا فَتَزَوَّجْتُهَا
