Mishkat al-Masabih 13 Marriage كتاب النكاح 200

وَعَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: ” ثَلَاثٌ جَدُّهُنَّ جَدٌّ وَهَزْلُهُنَّ جَدُّ: النِّكَاحُ وَالطَّلَاقُ وَالرِّجْعَةُ ” . رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ حَسَنٌ غَرِيب

Abu Huraira reported God’s Messenger as saying, “There are three things which, whether undertaken seriously or in jest, are treated as serious: marriage, divorce and taking back a wife after a divorce which is not final.” Tirmidhi and Abu Dawud transmitted it, Tirmidhi saying this is a hasan gharib tradition.
