Seeking to beget children

Narrated Jabir:

I was with Allah's Apostle in a Ghazwa, and when we returned, I wanted to hurry, while riding a slow camel. A rider came behind me. I looked back and saw that the rider was Allah's Apostle . He said (to me), "What makes you in such a hurry?" I replied, "I am newly married." He said, "Did you marry a virgin or a matron?" I replied, "(Not a virgin but) a matron." He said, "Why didn't you marry a young girl with whom you could play and who could play with you?" Then when we approached (Medina) and were going to enter (it), the Prophet ﷺ said, "Wait till you enter (your homes) at night (in the first part of the night) so that the ladies with unkempt hair may comb their hair, and those whose husbands have been absent (for a long time) may shave their pubic hair." (The sub-narrator, Hashim said: A reliable narrator told me that the Prophet added in this Hadith: "(Seek to beget) children! Children, O Jabir!")

حَدَّثَنَا مُسَدَّدٌ، عَنْ هُشَيْمٍ، عَنْ سَيَّارٍ، عَنِ الشَّعْبِيِّ، عَنْ جَابِرٍ، قَالَ كُنْتُ مَعَ رَسُولِ اللَّهِ ﷺ فِي غَزْوَةٍ، فَلَمَّا قَفَلْنَا تَعَجَّلْتُ عَلَى بَعِيرٍ قَطُوفٍ فَلَحِقَنِي رَاكِبٌ مِنْ خَلْفِي، فَالْتَفَتُّ فَإِذَا أَنَا بِرَسُولِ اللَّهِ ﷺ قَالَ " مَا يُعْجِلُكَ ". قُلْتُ إِنِّي حَدِيثُ عَهْدٍ بِعُرْسٍ. قَالَ " فَبِكْرًا تَزَوَّجْتَ أَمْ ثَيِّبًا ". قُلْتُ بَلْ ثَيِّبًا. قَالَ " فَهَلاَّ جَارِيَةً تُلاَعِبُهَا وَتُلاَعِبُكَ ". قَالَ فَلَمَّا قَدِمْنَا ذَهَبْنَا لِنَدْخُلَ فَقَالَ " أَمْهِلُوا حَتَّى تَدْخُلُوا لَيْلاً ـ أَىْ عِشَاءً ـ لِكَىْ تَمْتَشِطَ الشَّعِثَةُ وَتَسْتَحِدَّ الْمُغِيبَةُ ". قَالَ وَحَدَّثَنِي الثِّقَةُ أَنَّهُ قَالَ فِي هَذَا الْحَدِيثِ " الْكَيْسَ الْكَيْسَ يَا جَابِرُ ". يَعْنِي الْوَلَدَ.
