What should the parents Generally, Muslims of weak Imaan are extremely apologetic and defensive when kuffaar raise issues such as slavery in Islam, childmarriage, the marriage of Rasulullah (Sallallahu alayhi wasallam) to Hadhrat Aishah (Radhiyallahu anha), Rajm (stoning to death for adultery), etc. The attempt to answer and convince the kuffaar consists of stupid platitudes impregnated with apologetism which is the effect of ignorance and Imaani deficiency. The stupid, hateful criticism should not be entertained. Dismiss it with firmness. Say to the morons: We are proud of all these injunctions of Islam which are beyond the comprehension of your brains contaminated with kufr. Further, say to them as the Qur‟aan commands: "To you is your religion and to us is our religion. ---- We do not follow ignoramuses." do if their baaligh child becomes a flagrant murtad? Are they allowed to keep the child in the house as normal even if he/she is adamant on irtidaad?
