Aslam

Praise be to Allah.Firstly, you

say, “does this include those whom we loved but could not marry?”

The answer

to this is that it is not permissible for a Muslim man to form a relationship

with a non-mahram women, or for a Muslim woman to form a relationship

with a man or to have an emotional attachment to him, except for her

husband. See Questions nos. 9465, 5445, 1200.

Secondly, you

say, “Will the people who go to Heaven be reunited with their loved

ones who go to Hell?”

The answer

is, yes, the people of Paradise will be reunited with their loved ones

who went to Hell, if they were believers in Tawheed (the oneness of

Allaah). That will be by virtue of their intercession for them to be

brought forth from Hell and admitted to Paradise. The evidence for that

was narrated by al-Bukhaari in Kitaab al-Tawheed, no. 7440:

It was narrated that

Abu Sa’eed al-Khudri said: “We said, ‘O Messenger of Allaah! Shall we

see our Lord on the Day of Resurrection?’ He said, ‘Do you have any

difficulty in seeing the sun and the moon when the sky is clear?’ We

said, ‘No.’ He said, ‘So you will have no difficulty in seeing your

Lord on that Day, just as you have no difficulty in seeing the sun and

the moon (in a clear sky). …Then the bridge will be laid across Hell.’

We said, "O Messenger of Allaah! What is the bridge?’ He said,

‘It is a slippery (bridge) on which there are clamps and (hooks like)

thorns which are wide at one side and narrow at the other and have bent

ends. A plant with such thorns is found in Najd and is called al-Sa'daan.

Some of the believers will cross the bridge as quickly as the wink of

an eye, some others as quick as lightning, a strong wind, or fast horses

or she-camels. So some will be safe without any harm; some will be safe

after receiving some scratches, and some will fall down into Hell (Fire).

The last person will cross by being dragged (over the bridge). You (Muslims)

cannot be more pressing in claiming from me a right that has been clearly

proved to be yours than the believers in interceding with Almighty Allaah

for their (Muslim) brothers on that Day, when they see themselves safe.

They will say,

“O Allah! (Save) our brothers (for they) used to pray with us, fast

with us and also do good deeds with us.” Allah will say, “Go and take

out (of Hell) anyone in whose heart you find faith equal to the weight

of one (gold) Dinar.” Allah will forbid the Fire to burn the faces of

those sinners. They will go to them and find some of them in Hell (Fire)

up to their feet, and some up to the middle of their legs. So they will

take out those whom they will recognize and then they will return, and

Allah will say (to them), “Go and take out (of Hell) anyone in whose

heart you find faith equal to the weight of one half Dinar.” They will

take out whomever they will recognize and return, and then Allah will

say, “Go and take out (of Hell) anyone in whose heart you find faith

equal to the weight of an atom (or a small ant),” and so they will take

out all those whom they will recognize.’” Abu Sa’eed said, “If you do

not believe me, read, if you wish, ‘Surely, Allaah wrongs not even of the weight of an atom (or a small ant), but

if there is any good (done), He doubles it...’

[al-Nisaa’ 4:40 – interpretation of the meaning].” The Prophet

(peace and blessings of Allaah be upon him) said: “Then the Prophets

and Angels and the believers will intercede, and (last of all) the Almighty

(Allah) will say, ‘Now remains My Intercession. He will then hold a

handful of the Fire from which He will take out some people whose bodies

have been burnt, and they will be thrown into a river at the entrance

of Paradise, called the water of life. They will grow on its banks,

as a seed carried by the torrent grows…”

But for those

who believed in shirk, no intercession will benefit them. Allaah says

(interpretation of the meaning):

“Verily, Allaah forgives not that

partners should be set up with Him (in worship), but He forgives except

that (anything else) to whom He wills”

[al-Nisaa’

4:48]

Note that intercession

is of two types:

“The first

type is the kind of intercession that is the exclusive preserve of the

Messenger

(peace and blessings of Allaah be upon him), which is of varying kinds,

the greatest of which is the Great Intercession in the Station of praise

and glory (al-maqaam al-mahmood) which Allaah has promised to

him in the aayah (interpretation of the meaning):

‘And in

some parts of the night (also) offer the Salaah (prayer) with it (i.e.

recite the Qur’aan in the prayer) as an additional prayer (Tahajjud

optional prayer Nawaafil) for you (O Muhammad). It may be that your Lord will raise you to

Maqaam Mahmood (a station of praise and glory, i.e., the honour of intercession

on the Day of Resurrection)’

[al-Israa’

17:79]

This intercession

means that he will intercede for the people who are standing on the

Day of Resurrection, so that the distress they are suffering will be

reduced for them.

The second type is general intercession

on the part of the Messenger

(peace and blessings of Allaah be upon him) for all the believers. This

is of various kinds:

(i)Intercession for those

who deserve Hell, so that they will not enter it. This is indicated

by the words of the Messenger

(peace and blessings of Allaah be upon him), “There is no Muslim who

dies and forty men who do not associate anything with Allaah pray the

funeral prayer for him, but Allaah will accept their intercession for

him.” (narrated by Muslim, 2/655).

(ii)Intercession for those

who have entered Hell, so that they will be brought forth from it. It

was narrated that Abu Sa’eed al-Khudri said: “The Messenger of Allaah

(peace and blessings of Allaah be upon him) said: ‘By the One in Whose

hand is my soul,

You (Muslims) cannot

be more pressing in claiming from me a right that has been clearly proved

to be yours than the believers in interceding with the Almighty for

their (Muslim) brothers on that Day, when they see themselves safe.

They will say, “O Allah! (Save)

our brothers (for they) used to pray with us, fast with us and also

do good deeds with us.” Allah will say, “Go and take out (of Hell) everyone

whom you recognize.” Allah will forbid the Fire to burn the faces of

those sinners. So they will bring forth many people who were  in

the Fire up to their calves or their knees.” (Narrated by Muslim,269)

(iii)Intercession to raise the believers in status. This is because

of the du’aa’s of the believers for one another, as the Prophet

(peace and blessings of Allaah be upon him) said, making du’aa’ for

Abu Salamah: “O Allaah, forgive Abu Salamah, raise him in status among

those who are guided, make his grave spacious for him and fill it with

light, and protect his family who are left behind.” And there is the

du’aa’ for intercession as the Prophet

(peace and blessings of Allaah be upon him) said: “There is no Muslim

who dies and forty men who do not associate anything with Allaah pray

the funeral prayer for him, but Allaah will accept their intercession

for him.”
