Hadith 1621
۞
Disputes (shiqaq) can arise from both the husband and the wife. This is related to what Allah (swt), the Mighty and Majestic, has said
"And if you fear discord between them, appoint an arbitrator from his family and an arbitrator from her family." (Surah An-Nisa 4:35)
The husband should choose a representative from his family, and the wife should choose a representative from hers. These two arbitrators will then meet to decide either on separation or reconciliation.
If they intend reconciliation, they may proceed with it without seeking further permission. However, if they wish to separate the couple, they are not allowed to do so unless they seek the consent of both the husband and the wife.
الشِّقَاقُ قَدْ يَكُونُ مِنَ الْمَرْأَةِ وَ الرَّجُلِ جَمِيعاً وَ هُوَ مِمَّا قَالَ اللَّهُ عَزَّ وَ جَلَّ
وَ إِنْ خِفْتُمْ شِقاقَ بَيْنِهِما فَابْعَثُوا حَكَماً مِنْ أَهْلِهِ وَ حَكَماً مِنْ أَهْلِها
فَيَخْتَارُ الرَّجُلُ رَجُلًا وَ تَخْتَارُ الْمَرْأَةُ رَجُلًا فَيَجْتَمِعَانِ عَلَى فُرْقَةٍ أَوْ عَلَى صُلْحٍ فَإِنْ أَرَادَا الْإِصْلَاحَ أَصْلَحَا مِنْ غَيْرِ أَنْ يَسْتَأْمِرَا وَ إِنْ أَرَادَا أَنْ يُفَرِّقَا فَلَيْسَ لَهُمَا أَنْ يُفَرِّقَا إِلَّا بَعْدَ أَنْ يَسْتَأْمِرَا الزَّوْجَ وَ الْمَرْأَةَ.
