Engagment, - Dought & clear, - * How can a man know if a woman will be a loving and fertile wife before marriage?

It says in the hadeeth: "Marry women who are loving and fertile…" but
how can a man know if a woman is loving and fertile before marriage?.
-
Praise be to Allaah.
It was narrated that Ma'qil ibn Yasaar said: A man came to the
Messenger of Allaah (peace and blessings of Allaah be upon him) and
said: "O Messenger of Allaah, I have found a woman who is from a good
family and is beautiful, but she does not bear children; should I
marry her?" He told him not to. Then he came to him a second time and
said something similar and he told him not to marry her. Then he came
to him a third time and said something similar and he (peace and
blessings of Allaah be upon him) said: "Marry the one who is loving
and fertile, for I will be proud of your great numbers."
Narrated by Abu Dawood, 2050; al-Nasaa'i, 3227; classed as saheeh by
Shaykh al-Albaani (may Allaah have mercy on him) inAdaab al-Zafaaf, p.
132.
There are two ways of knowing whether a woman will be fertile:
1 – By looking at her mother and sisters
2 – If she has been married before; that will be known from her
previous marriage.
Shaykh 'Abd al-'Azeem Abaadi said in'Awn al-Ma'bood(6/33): Marry the
one who is loving, means, the one who loves her husband; and the one
who is fertile, is the one who bears a lot of children.
It may be understood from this that if the one who is fertile is not
loving, it is not recommended to marry her, and if the one who is
loving is not fertile, then the purpose of marriage, which is to
increase the numbers of the ummah by bearing many children, will not
be achieved. These two qualities may be known in the case of virgins
from their relatives, because relatives are usually similar,
physically and in attitude, to one another.
And Allaah knows best.
