Masruq (may Allah have mercy on him) said: Sayyiduna Muawiyah (may Allah be pleased with him) considered a Muslim to be the heir of a disbeliever, but did not consider a disbeliever to be the heir of a Muslim. Shu’bi (may Allah have mercy on him) said: Masruq said: In Islam, I have not found any decision better than this. Imam Darimi (may Allah have mercy on him) was asked: Do you also say the same? He said: No (i.e., inheritance between the two is not permissible, as will be mentioned ahead in the authentic hadith).
