28. " the believers should not take the infidels as their friends,
rather than the believers, and whoever does that then nothing of allah is his,
except when you guard yourselves against them, guarding carefully;
and allah warns you to be cautious of (disobeying) him;
and toward allah is the destination."

commentary:
in this holy verse, the feature of the foreign policy, encountering
with the unbelievers and that assuming the mastership of disbelievers is
on a par with losing the mastership of allah, the necessary conditions
of concealing of faith /taqiyyah/ and prevention of abusing it, have been
stated.

explanations:
1. it is prohibited that the believers assume the mastership of
disbelievers.

" the believers should not take the infidels as their friends,
rather than the believers, ..."

if the muslims of the world had acted according to only this
principle, the status of the islamic countries would not be in such a
condition that it is now.

2. not only the acceptance of the mastership of disbelievers, but
also being content with infidelity and approving it, is unlawful for the
believers.

"... and whoever does that then nothing of allah is his, ..."

3. the apparent connexion with disbeleivers for reaching some
higher aims, in some circumstances, is permissible.

4. political relationship should not result in accepting domination
of, or heartily connexion with, the infidels.

"... except when you guard yourselves against them, guarding carefully; ..."

5. concealing of faith is only for the sake of protection of
religion. beware not to be attracted by the infidels under the pretext of
concealment of faith, and not to misuse this concept!

"... allah warns you to be cautious of (disobeying) him; ..."

6. in circumstances that the basis of religion is in danger,
everything must be devoted, and everybody should only be in awe of
allah.

"... and to allah is the destination."

7. connection or disconnection ought to be performed on the
basis of contemplation and belief, not upon the basis of racial, tribal and
family affections, or economical concerns, and so on.

8. in place of infidels, muslims must make friends and
cammunicate with each other among themselves.
