It is not permissible to    call kuffaar to Islam by means of religious songs (nasheeds) accompanied by musical    instruments
Question

When we want to attract Christians to Islam, is it permissible to use religious songs accompanied by music? Is it permissible to have a group called a religious group because they sing religious songs accompanied by musical instruments?
Praise be to Allah.In my opinion there is no need to attract people in this manner; you should use permissible means such as listening to Qur’aan with proper tajweed and tarteel (correct recitation) and listening to eloquent ahaadeeth which move the listener, and beneficial, moving poems (qaseedahs) and nasheeds. You can also provide clear proof of what is good about Islam and explain its teachings and noble aims which will demonstrate that it is the religion that befits the natural inclinations of man (deen al-fitrah) and encompasses all the interests of mankind. Whoever can only be attracted by things that include forbidden elements such as singing, instruments and music is no good and I do not think that he can be attracted to Islam at all. And Allah knows best.
