Sharing Visits to one’s Wives Equally - Section 1
عَنِ ابْنِ عَبَّاسٍ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قُبِضَ عَنْ تِسْعِ نِسْوَةٍ وَكَانَ يقسم مِنْهُنَّ لثمان
Ibn ‘Abbas said that when God’s Messenger died he left nine wives, eight of whom he used to visit equally. (The next tradition explains this) (Bukhari and Muslim.)
