Conciliation between Muslims is permissible except the conciliation that makes something lawful unlawful or makes unlawful thing lawful.
(Part No. 14; Page No. 200)
Forcing one of the two parties to offer any sacrifice or anything is not permissible except if this is done willingly and of his own choice because of Allah's statement:
And eat up not one another’s property unjustly (in any illegal way e.g. stealing, robbing, deceiving, etc.)
The Prophet (peace be upon him) stated:
The property of a Muslim is unlawful (to take), unless (he gives it) willingly.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
