Allah Has Created a Powerful Love among Muslims

The love among Muslims is a naturally occurring love resulting from
a faith-based sincerity. Is not based on any self-interest;
believers love one another solely for Allah's approval. This
sincere love also brings with it a lofty conception of humility.
And when love and humility are combined together, the result is a
powerful bond among Muslims.
The people to whom believers most direct their love as
manifestations of Allah are their brothers in faith. As our Lord
says in one verse, "The faithful are brothers..." (Surat
al-Hujurat, 10), Muslims are one anothers brothers. Therefore, as
with blood brothers, the relationship between Muslims is based on a
profound love, and they watch over and protect one another.
Allah gives love to the heart of every Muslim who loves Him, fears
Him and genuinely strives to seek His approval. Our Lord states that
it is His Presence that creates love among believers:
" As for those who have faith and do right actions, the All-Merciful
will bestow His love on them." (Surah Maryam, 96)
Since these people love Allah, they will also love His creations and
feel affection and compassion for them. They will wish to protect
them and seek the best for them. As Allah tells believers, whom He
has made his best and most virtuous servants:
" Say: 'I do not ask you for any wage for this –except for you to
love your near of kin. If anyone does a good action,We will
increase the good of it for him. Allah is Ever-Forgiving,
Ever-Thankful'." (Surat ash-Shura, 23)
Muslims Loving One Another in This World Is a Moral Virtue of Paradise
It is incompatible with Qur'anic moral values for the bond of love
that Muslims feel for one another to be limited to a small
community. That bond of love must include all sects and communities
and even the entire Islamic world. Allah disapproves of coldness,
and even conflict, between sects and communities. All Muslims must
hope to enter paradise and strive for that by doing good works. But
in order to enter paradise they must love one another. In paradise,
all Muslims are a single community, and verses reveal that Muslims
will recognize one another there, talk with one another, be friends
and love one another:
" in Gardens of Delight. A large group of the earlier people but few
of the later ones.
On sumptuous woven couches, reclining on them face to face." (Surat
al-Waki'ah, 12-16)
Another verse reveals that brotherhood, profound love and devotion
among Muslims is one of the features of paradise as follows.
" We will strip away any rancor in their hearts – brothers, resting
on couches face-to-face." (Surat al-Hijr, 47)
Muslims are a single community in paradise, and there are no
communities or groups that do not love another, and everyone is
equal. There is also an obligation for his model in paradise as
described in the verses to be adopted and implemented in this
world, too. Allah warns Muslims in another verse that they must be
very considerate of one another and that there must be a bond of
love between them, and He reveals that this will be pleasing to
Him:
" Allah loves those who fight in His Way in ranks like well-built
walls." (Surat as-Saff, 4)
