Is it permissible for the father of the man to see his son's fiancée?
-
Praise be to Allah.
It is not permissible for the father to see his son's fiancée, because
she is a non-mahram to him. It is only permissible for his son to see
her with special permission from sharee'ah, in order to create harmony
and affection after marriage. But no exception has been narrated with
regard to the man's father; in that case the original prohibition on
seeing her remains in effect, and she is like any other woman who is a
non-mahram to him. So he is enjoined to avert his gaze from her, not
to be alone with her and not to shake hands with her.
But when his son does the marriage contract with his fiancée, she
becomes his wife, even if he has not consummated the marriage with
her, and even if in your country she is still called a fiancée after
doing the marriage contract. This customary naming of the matter does
not affect anything, so long as the son's marriage contract has been
done. In that case it becomes permissible for the father to look at
his son's wife, because she has become a mahram to him, as Allah, may
He be exalted, says (interpretation of the meaning):"Forbidden to you
(for marriage) are: your mothers, your daughters... the wives of your
sons who (spring) from your own loins" [an-Nisa' 4:23].
And Allah knows best.

Engagment, - Dought & clear, - * He does not offer the prayers on time because of his work; should she accept him as a husband?

If someone who is trying to establish the 5 daily prayer but is
struggling for example when they are at work and they get very busy
they miss it but them make it up. but most of the time they pray at
work. but they really want to change are they considered to be a
kaffir and you should not marry them ect. I take the opinion that
someone who abandons prayer is a kaffir but what are the opinions and
evidence about the one who is trying to change and establish prayer. I
have a proposal from a brother like this who my family know quite
well. He is a good character but struggling regarding this but wants
to marry someone who can help him be a better muslim and encourage and
help him in his deen.

Firstly:
The one who does not pray at all is a kaafir according to the correct
scholarly opinion. See question no. 5208.
As for the one who prays sometimes and not at other times, some of the
scholars are of the view that he is also a kaafir. This view was
narrated from a number of the Sahaabah, and fatwas to this effect have
been issued by the Standing Committee for Issuing Fatwas, foremost
among whom was Shaykh 'Abd al-'Azeez ibn Baaz (may Allah have mercy on
him).
Others are of the view that he is not to be regarded as a kaafir
unless he does not pray at all; these scholars include Shaykh al-Islam
Ibn Taymiyah (may Allah have mercy on him) and Shaykh Ibn 'Uthaymeen
(may Allah have mercy on him).
See question no. 52923and 83165
Work is not an excuse for delaying prayer until the time for it has
ended, because prayer only takes a few minutes.
If the one who wants to propose to you delays some of the prayers, we
do not advise you to marry him, because he is a kaafir according to
some of the scholars, and he is an evildoer who is committing a grave
major sin according to others.
Allah, may He be exalted, says (interpretation of the meaning):
"Then, there has succeeded them a posterity who have given up As-Salat
(the prayers) (i.e. made their Salat (prayers) to be lost, either by
not offering them or by not offering them perfectly or by not offering
them in their proper fixed times, etc.) and have followed lusts. So
they will be thrown in Hell"
[Maryam 19:50].
Ibn Mas'ood (may Allah be pleased with him) said concerning al-ghayy
(translated above as "Hell"): It is a valley in Hell, very deep and
with a foul taste.
If he announces that he has repented and has resolved to offer the
prayers on time, and you think that he is righteous in other aspects,
then there is nothing wrong with marrying him.
And Allah knows best.
