Asking a kaafir to make dua
Q: Can a person ask a kaafir to make dua without any belief that their idols would fulfil their wish. He believes that only Allah Ta'ala can fulfil the wish of the kaafir and that there is no other God that exists except Allah, but just saying "dua karna-pray for me/us" to a kaafir, would this constitute kufr which takes a person out of the fold of Islam?
