‘Non-Muslims’ instead of ‘Kuffar’

An extract from Shaykh Yusuf al-Qaradawi:

In calling (da’wa) others with wisdom and beautiful preaching and arguing with that which is best, which the Muslims are required to do – it is advisable (particularly in the age of globalisation) to not address those whom we differ with, as kuffar, even though we believe that they are so. This is especially in the case of the People of the Book (Christians and Jews).
