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

Al-Mughira b. Shu'ba said

I asked a woman in marriage and God’s Messenger asked me whether I had looked at her. When I replied that I had not, he said, “Then look at her, for it is better that there should be love between you.” Ahmad, Tirmidhi, Nasa'i, Ibn Majah and Darimi transmitted it.
