Mishkat al-Masabih 13 Marriage كتاب النكاح 27

عَنْ جَابِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا خَطَبَ أَحَدُكُمُ الْمَرْأَةَ فَإِنِ اسْتَطَاعَ أَنْ يَنْظُرَ إِلَى مَا يَدْعُوهُ إِلَى نِكَاحهَا فَلْيفْعَل» . رَوَاهُ أَبُو دَاوُد

Jabir reported God’s Messenger as saying, “When one of you asks a woman in marriage, if he is able to look at what will induce him to marry her, he should do so.” Abu Dawud transmitted it.
