Jabir bin Abdullah reported,

I was with the Messenger of Allah ﷺ on a military expedition. When we were returning, I hurried ahead on a slow camel. A rider came up behind me, and when I turned, there was the Messenger of Allah ﷺ.He asked, "What is making you hurry?"I replied, "I am newly married."He asked, "Did you marry a virgin or a previously married woman?"I said, "A previously married woman."He said, "Why not a young Jariya you could play with and who could play with you?"When we arrived, we were about to enter our homes, but he said, "Wait until you enter at night, meaning in the evening, so that the disheveled wife may comb her hair and the woman whose husband has been away may shave."The narrator said, A trustworthy person told me that he said in this hadith, "Be wise, be wise, Jabir," meaning about having children.

حدثنا مسدد عن هشيم عن سيار عن الشعبي

عن جابر قال

كنت مع رسول الله ﷺ في غزوة فلما قفلنا تعجلت على بعير قطوف فلحقني راكب من خلفي فالتفت فإذا أنا برسول الله ﷺ قال ما يعجلك قلت إني حديث عهد بعرس قال فبكرا تزوجت أم ثيبا قلت بل ثيبا قال فهلا جارية تلاعبها وتلاعبك قال فلما قدمنا ذهبنا لندخل فقال أمهلوا حتى تدخلوا ليلا أي عشاء لكي تمتشط الشعثة وتستحد المغيبة قال وحدثني الثقة أنه قال في هذا الحديث الكيس الكيس يا جابر يعني الولد
