Volume 7, Book 62, Number 16:
Narrated Jabir bin Abdullah:

While we were returning from a Ghazwa (Holy Battle) with the Prophet, I started driving my camel fast, as it was a lazy camel A rider came behind me and pricked my camel with a spear he had with him, and then my camel started running as fast as the best camel you may see. Behold! The rider was the Prophet himself. He said, '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, "A matron." He said, "Why didn't you marry a young girl so that you may play with her and she with you?" When we were about to enter (Medina), the Prophet said, "Wait so that you may enter (Medina) at night so that the lady of unkempt hair may comb her hair and the one whose husband has been absent may shave her pubic region.

Jabir bin Abdullah radhiallahu anhus father had passed away and so he married an older woman who could look after his sisters as other hadiths explained in full regarding the story. As for the men stopping. in those days there werent cell phones, the women were given time to 'prepare' for their husbands...does he find something wrong with that..seriously? what planet is he on if so?

the hadith, narrated bukhari:
Narrated Jabir bin 'Abdullah: I was accompanying the Prophet on a journey and was riding a slow camel that was lagging behind the others. The Prophet passed by me and asked, "Who is this?" I replied, "Jabir bin 'Abdullah." He asked, "What is the matter, (why are you late)?" I replied, "I am riding a slow camel." He asked, "Do you have a stick?" I replied in the affirmative. He said, "Give it to me." When I gave it to him, he beat the camel and rebuked it. Then that camel surpassed the others thenceforth. The Prophet said, "Sell it to me." I replied, "It is (a gift) for you, O Allah's Apostle." He said, "Sell it to me. I have bought it for four Dinars (gold pieces) and you can keep on riding it till Medina." When we approached Medina, I started going (towards my house). The Prophet said, "Where are you going?" I Sad, "I have married a widow." He said, "Why have you not married a virgin to fondle with each other?" I said, "My father died and left daughters, so I decided to marry a widow (an experienced woman) (to look after them)." He said, "Well done." When we reached Medina, Allah's Apostle said, "O Bilal, pay him (the price of the camel) and give him extra money." Bilal gave me four Dinars and one Qirat extra. (A sub-narrator said): Jabir added, "The extra Qirat of Allah's Apostle never parted from me." The Qirat was always in Jabir bin 'Abdullah's purse.
