It is incumbent that man not adopt the way of hypocrisy. For example, if a Hindu (despite being a ruler or high official) were to suggest that Ram and Rahim are one and the same, a person should not agree with such an opinion thoughtlessly. Allah the Exalted does not forbid one from treating others with civility. One should always respond politely. It is not wise to make comments that unnecessarily enrage others and which result in pointless conflict. But, a person should never conceal the truth. An individual who pliantly accepts the false statements of others eventually becomes a disbeliever.
یارغالب شوکہ تاغالب شوی
Become the friend of he who is dominant, so that you too may become dominant.
Allah the Exalted should always be honoured and respected. There is not a single aspect of our religion that is at odds with civility.
(Hazrat Mirza Ghulam Ahmadas, Malfuzat, Vol. 1, p. 6)
