" I bear witness that there is no god but Allah and Muhammad is the messenger "
We have seen many people reverting to Islam throughout the world. Surprisingly, many reverts are learned people or people with wisdom, people with good academic background.
In Germany, we see on YouTube youngsters are queueing up to recite the syahadah. They do so not because of pressure from the Muslims but they see the new future in Islam. They analysed the Quran and of course the most important is Allah gave them the light (nur) and guidance (hidayah).
The duty of a Muslim and Muslimah are to tell the truth about the real teaching of Islam as the way of life and that's all. The rest will be up to Allah. When a person revert to Islam it is not because someone has the power to do so. It is Allah who choose him or her to come back to Islam.
