103. " and hold fast by the cord of allah all together, and do not separate;
and remember allah's favour on you when you were enemies (of each other)
then he united your hearts with (mutual) love,
and thus you became brethren by his favour while you were on
a brink of a pit of fire then he delivered you from it!
even so allah makes clear his signs for you,
so that you may be guided."

commentary:
an invitation to union;

in this verse, the ultimate subject, which is the problem of unity and
standing against any separation, is referred to. it says:

" and hold fast by the cord of allah all together,
and do not separate;..."

the opinions are divided among the commentators as to the meaning
of the term /hablullah/ ` the cord of allah '. and in islamic literature
there are also varieties of narrations about it. but there is no difference in
the basic meaning of them, because the purpose of `the cord of allah' is
any means of connection with the pure essence of allah, whether it be
the qur'an, the prophet (p.b.u.h.) or his progeny, ahlul-bayt (a.s.).

then, the holy qur'an points to the great bounty of union and
brotherhood among muslims. it invites them that they comtemplate upon
the miserable conditions of the past and to compare its dispersion with
union of islam. it says:

"... and remember allah's favour on you when you were enemies (of each other)
then he united your hearts with (mutual) love, and thus you
became brethren by his favour ..."

here, the subject of love and unity of the hearts of the believers is
attributed to allah, where it says:

"... then he united your hearts with (mutual) love, ...".

by this phenomenon, he has pointed to a social miracle of islam,
because if we refer properly to the background of the old enmity of arab,
we will realize that how a slight and simple subject could lighten the fire of
a bloody war between them. this proves that it was impossible to form one
united nation from that unaware, ignorant, separated people through the
ordinary ways.

the importance of unity and brotherhood among the hostile arab
tribes has not remained concealed even from the eyes of the non-muslim
scientists and historians, who totally speak of it with much wonder.
then, the qur'an continues saying:

"... while you were on a brink of a pit of fire then he delivered
you from it ! ... "

that is, allah delivered you from that horrible precipice and led you
to a safe and sound point, viz. the point of `brotherhood and love'.

the arabic word /nar/ `fire' mentioned in the above verse is
metaphorically used for the fights and conflicts which, in the age of
ignorance, every moment could happen by a pretext among arabs.

at the end of the verse, to emphasize it more, it says:

"... even so, allah makes clear his signs for you, so that you may be guided."
