الجواب حامدا و مصلیا
Whoever accepts Mirza Ghulam Ahmad Qadiani as a Nabi is an apostate, heretic and out of the fold of Islam. It is impermissible to move with such a person due to the following facts.
1 Cooperation with Qadianis and their moral boosting
2 Due to such activities the general public tend to think Qadianis as a Sect among Muslims
3 By this, Qadianis get a proper opportunity to lay their traps and mislead Muslims
Therefore, it is necessary to boycott Qadianis in transactions and all other sort of activities. Even if the person who interacts with Qadianis admits them to be wrong, yet it is a condemnable act to have connections with those who blaspheme Nabi Akram Sallallahu Alaihi Wa Sallam and the other Anbiya Alaihimus Salathu Wassalaam. Hence it is necessary to prevent the concerned Qadiani from interacting with you all and participating in Salathul Janaza.
