Al-Mughirah ibn Shu’bah reported: He proposed to a woman in marriage and the Prophet, peace and blessings be upon him, said, “Look at her, for it is the best way to make lasting affection between you.”
Al-Tirmidhi said, “Some of the people of knowledge adhered to this tradition. They said: There is nothing wrong with looking at her as long as he does not see parts of her forbidden to see.”

عَنْ الْمُغِيرَةِ بْنِ شُعْبَةَ أَنَّهُ خَطَبَ امْرَأَةً فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ انْظُرْ إِلَيْهَا فَإِنَّهُ أَحْرَى أَنْ يُؤْدَمَ بَيْنَكُمَا
قال الترمذي ذَهَبَ بَعْضُ أَهْلِ الْعِلْمِ إِلَى هَذَا الْحَدِيثِ وَقَالُوا لَا بَأْسَ أَنْ يَنْظُرَ إِلَيْهَا مَا لَمْ يَرَ مِنْهَا مُحَرَّمًا
