A Woman Who Gives Herself to Him

S 33:50 Prophet, we have made lawful for you your husbands whom you have given their wages to and what your right hand possesses from what Allah has given you as booty and the daughters of your paternal uncles and the daughters of your paternal aunts and the daughters of your maternal uncles and the daughters of your maternal aunts who emigrated with you and a believing woman who has given herself to the prophet if the prophet wants to futter her--exclusively for you, excluding the believers. We knew what we made obligatory upon them concerning their husbands and what their right hands have possessed, that here should be no difficulty upon you. And Allah was a forgiver, merciful.

Narrated 'Aishah:

It was narrated that 'Aishah said: "I used to feel jealous of those (women) who offered themselves (in marriage) to the Prophet and I said: 'Would a free woman offer herself?' Then Allah, the Mighty and Sublime, revealed: 'You can postpone whom you will of them, and you may receive whom you will.' I said: 'By Allah, I see that your Lord is quick to respond to your wishes.'"

Narrated Sahl bin Sa`d:

While we were sitting in the company of the Prophet (ﷺ) a woman came to him and presented herself (for marriage) to him. The Prophet (ﷺ) looked at her, lowering his eyes and raising them, but did not give a reply. One of his companions said, "Marry her to me O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) asked (him), "Have you got anything?" He said, "I have got nothing." The Prophet (ﷺ) said, "Not even an iron ring?" He Sa`d, "Not even an iron ring, but I will tear my garment into two halves and give her one half and keep the other half." The Prophet; said, "No. Do you know some of the Qur'an (by heart)?" He said, "Yes." The Prophet (ﷺ) said, "Go, I have agreed to marry her to you with what you know of the Qur'an (as her Mahr)."

This slut who offered herself to him was immediately given away to a guy in the crowd. "for marriage" is the translator's interpolation.

Side note: He asks him if he had an iron ring to give her.

Muhammad ibn 'Abdullah reported that a man came to the Prophet, may Allah bless him and grant him peace, wearing a gold signet-ring on his finger. The Prophet, may Allah bless him and grant him peace, turned away from him. When the man saw his dislike of the gold, he threw the ring away. He made an iron ring and wore that. He came to the Prophet, may Allah bless him and grant him peace, who said, "This is worse. This is the ornament of the people of the Fire." The man went away, threw it off and put on a silver ring and the Prophet, may Allah bless him and grant him peace, did not say anything about it."

The founder of Islam, we are told, had one.

Iyas bin Al-Harith bin Al-Mu'aiqib narrated that his grandfather Mu'aiqib said:

"The ring of the Prophet [SAW] was made of iron with silver twisted around it." He said: "And sometimes it was on my hand." And Mu'aiqib was the keeper of the ring of the Messenger of Allah [SAW].

But back to our topic. If the women offering themselves were doing so in marriage, we read this:

It was narrated from Abu Hurairah that:

the Messenger of Allah said: “No woman should arrange the marriage of another woman, and no woman should arrange her own marriage. The adulteress is the one who arranges her own marriage.”
