The texts
شُرُوطُ الدَّاعِيَةِ: ٢١ - يُشْتَرَطُ فِي الدَّاعِيَةِ أَنْ يَكُونَ مُكَلَّفًا (أَيْ مُسْلِمًا عَاقِلاً بَالِغًا) وَأَنْ يَكُونَ عَالِمًا عَادِلاً، وَلاَ خِلاَفَ فِي أَنَّ الْمَرْأَةَ مُكَلَّفَةٌ بِالدَّعْوَةِ، مُشَارِكَةٌ لِلرَّجُل فِيهَا. وَرَاجِعْ هُنَا مُصْطَلَحَ: (الأَْمْرُ بِالْمَعْرُوفِ) (ف ٤) .
