Narrated Abu Huraira:
حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ ، حَدَّثَنَا ابْنُ الْمُبَارَكِ ، عَنْ مَعْمَرٍ ، عَنْ هَمَّامٍ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " غَزَا نَبِيٌّ مِنَ الأَنْبِيَاءِ فَقَالَ لِقَوْمِهِ لاَ يَتْبَعْنِي رَجُلٌ مَلَكَ بُضْعَ امْرَأَةٍ وَهْوَ يُرِيدُ أَنْ يَبْنِيَ بِهَا وَلَمْ يَبْنِ بِهَا " .
The Prophet (ﷺ) said, "A prophet among the prophets went for a military expedition and said to his people: "A man who has married a lady and wants to consummate his marriage with her and he has not done so yet, should not accompany me.' "
