The Prophet (ﷺ) said, "If you enter (your town) at night (after coming from a journey), do not enter upon your family till the woman whose husband was absent (from the house) shaves her pubic hair and the woman with unkempt hair, combs her hair" Allah's Messenger (ﷺ) further said, "(O Jabir!) Seek to have offspring, seek to have offspring!"
Sahih al-Bukhari Book 67, Hadith 179
← Previous Hadith I was with Allah's Messenger (ﷺ) 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 Messenger (ﷺ) . 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 (ﷺ) added in this Hadith: "(Seek to beget) children! Children, O Jabir!")

Sahih al-Bukhari Book 67, Hadith 178 Next Hadith → We were with the Prophet (ﷺ) in Ghazwa, and when we returned and approached Medina, I wanted to hurry while riding a slow camel. A rider overtook me and pricked my camel with a spear which he had, whereupon my camel started running as fast as any other fast camel you may see. I looked back, and behold, the rider was Allah's Messenger (ﷺ) . I said, "O Allah's Messenger (ﷺ)! I am newly married " He asked, "Have you got married?" I replied, "Yes." He said, "A virgin or a matron?" I replied, "(Not a virgin) but a matron" He said, "Why didn't you marry a young girl so that you could play with her and she with you?" When we reached (near Medina) and were going to enter it, the Prophet (ﷺ) said, "Wait till you enter your home early in the night so that the lady whose hair is unkempt may comb her hair and that the lady whose husband has been away may shave her pubic hair."
