How do the dhimmi have to behave if a relative decides to become a muslim

The conversion to Islamism was mostly forced, relatives supported that decision. The life of the dhimmis was very difficult, with much pressure, massacres humiliations, unjust accusations with death penalty. Many people converted to Islam to avoid paying the yizia, jarach, offer their children in the devsirme and other discriminatory practices. Conversion brought economic and social benefits, for example avoid the payment of two taxes, one for the amount of land you owned and another by the number of inhabitants, you could also own weapons and your word would have more value, since the word of a non-Muslim is worth 1/4 of that of a Muslim, also a Muslim man can marry a woman of other beliefs, while the Muslim woman can only marry a Muslim man.
