It is not only forbidden to compel someone to accept Islam - it is impossible to do so.
Please consider the meaning of the word"Islam" before continuing to read: ['Islam'; Ar. from the root 'slm' (silm), to be in peaceful submission; to surrender; to obey; peace; "Islam" lit. 'The active willful surrender, submission, obedience, in purity to the will of another (Allah) in complete peace.']
The understanding from the meaning of the word "Islam" itself makes it clear that there is no way that you could possibly force someone to do something that requires them to do it of their own free will and accord. If someone were "forced to enter Islam" then it would not be "Islam" anyway, as a condition of "Islam" is that it is by free choice in peace. Forcing people into Islam is totally illogical and certainly not acceptable in concept nor practice
