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 اللهِ ﷺ إِذَا خَطَبَ أَحَدُكُمُ الْمَرْأَةَ فَإِنْ اسْتَطَاعَ أَنْ يَنْظُرَ مِنْهَا إِلَى مَا يَدْعُوهُ إِلَى نِكَاحِهَا فَلْيَفْعَلْ قَالَ فَخَطَبْتُ جَارِيَةً مِنْ بَنِي سَلِمَةَ فَكُنْتُ أَخْتَبِئُ لَهَا تَحْتَ الْكَرَبِ حَتَّى رَأَيْتُ مِنْهَا بَعْضَ مَا دَعَانِي إِلَى نِكَاحِهَا فَتَزَوَّجْتُهَا
