It was narrated that Al-Mughirah bin Shu'bah said: "I proposed marriage to a woman during the time of the Messenger of Allah, and the Prophet said: 'Have you seen her?' I said: 'No.' He said: 'Look at her, for that is more likely to create love between you.'"
خَطَبْتُ امْرَأَةً عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَقَالَ النَّبِيُّ ﷺ أَنَظَرْتَ إِلَيْهَا قُلْتُ لاَ قَالَ فَانْظُرْ إِلَيْهَا فَإِنَّهُ أَجْدَرُ أَنْ يُؤْدَمَ بَيْنَكُمَا
