Sayyiduna Abu Hurayra (Allah be pleased with him) narrates:
I was in the company of the Messenger of Allah (Allah bless him & give him peace) when a man came and informed him that he had contracted to marry a woman of the Ansar. The Messenger of Allah (Allah bless him & give him peace) said to him: “Did you cast a glance at her? He said: No. He said: “Go and look at her, for there is something in the eyes of the Ansar”. (Sahih Muslim, no. 1423)
The great Hadith and Shafi’i Fiqh scholar, Imam al-Nawawi (Allah have mercy on him) states:
“…In the Hadith (of Abu Hurayra mentioned first) there is recommendation of looking at the face of the woman one is intending to marry. This is the opinion of the Shafi’i School, the School of Malik, Abu Hanifa, all the scholars of Kufa, Ahmad and the majority of the Ulama. Qadhi (Iyadh) has narrated from a group (of scholars) that it is disliked but that is incorrect and contrary to the clear text of this Hadith, and contrary to the consensus (ijma’)
of the Ummah…Then, it is permitted for him to look at her palms and face only, for they are not considered to be part of the nakedness (awrah),
and also because by looking at the face, one is able to determine her beauty or otherwise and by looking at her hands one is able to determine the chubbiness of the body or otherwise. This is the opinion of Shafi school and the view of most others.”
(al-Minhaj Sharh Sahih Muslim, p. 1068)
The Hadith you mentioned:
Sayyiduna Jabir (Allah be pleased with him) narrates that the Messenger of Allah (Allah bless him & give him peace) said: “When one of you proposes to a woman for marriage, then if he is able to look at what will induce him to marry her, he should do so.” (Sunan Abu Dawud and Musnad Ahmad)
Some people think that the hadith narrated by Sayyiduna Jabir means that they can see any body parts of the women but this is wrong as the explanation below proves:
Mulla Ali al-Qari, the great Muhaddith and Hanafi
Imam, states in Mirqat al-Mafatih, quoting from Allama Teebi that the meaning of the Messenger of Allah’s (Allah bless him & give him peace) statement “if he is able to look at what will induce him to marry her, he should do so” (in the Hadith of Jabir recorded by Imam Abu Dawud, mentioned above) is either wealth, status, beauty and religion (deen).” (Mirqat al-Mafatih, 6/198)
To sum up, the only body parts a man can see of a non-Mahram woman whom he has some interest into marrying, are the hands and face which are not part of the awrah. If one wants more descriptions of the woman's body part, one should send a female relative to describe her to you.
If one decides to marry someone, it is for the man permitted to look at the woman’s face and hands only. This is the opinion of the majority of the scholars (jumhur), including the Hanafis, as mentioned earlier. Some individual scholars (such as Imam al-Awza’i, Ibn Hazam and Dawud Zahiri) did permit looking at other than the hands and face but this is not the mainstream opinion.
And Allah knows best.
