Praise be to Allah.
Thank you for your nice letter. We are happy to respond to your request, and we are especially pleased to hear of your interest in the religion of Islam. We suggest that if you study the contrast between Islam and other religions, you will see the superiority of this religion over all others, in terms of its comprehensiveness, solid foundations, approach to issues, the soundness of its message and the justice of its rules. (Please also see Questions #s 219 and 3143). This superiority alone is sufficient reason for anyone to embrace Islam, let alone the fact that Islam has superceded all other religions, and Allaah does not accept any other religion from His slaves, as He says (interpretation of the meaning):
“And whoever seeks a religion other than Islaam, it will never be accepted of him, and in the hereafter he will be one of the losers.” [Aal ‘Imraan 3:85]
