Hadith #5

وَ بِإِسْنَادِهِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ بَلَغَ النَّبِيَّ ( صلى الله عليه وآله ) أَنَّ أَبَا أَيُّوبَ يُرِيدُ أَنْ يُطَلِّقَ امْرَأَتَهُ فَقَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) إِنَّ طَلَاقَ أُمِّ أَيُّوبَ لَحُوبٌ .

5. Through the same chain of narrators as that of the previous Hadith, the following is narrated: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that the Holy Prophet, was informed about abu Ayyub’s divorcing his wife. The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, then said, ‘Divorcing ‘Umm (mother of) Ayyub is a sin."
