Athar regarding adornment of slave-girls

> حدثنا أبو بكر قال: حدثنا وكيع، قال: حدثنا أسامة بن زيد، عن أبي حازم، عن سهل بن سعد: أنهم مروا عليه بجارية قد زينت، فدعا بها ونظر إليها وأجلسها في حجره ومسح على رأسها ودعا لها بالبركة > > 22790- Narrated by Waki: Usamah ibn Zaid narrated to us, from Abu Hazim, from Sahl ibn Sa'd: They passed by him with a slave girl who had been adorned. So he called for her, looked at her, seated her in his lap, wiped over her head, and prayed for her with blessings. > > حدثنا أبو بكر قال: حدثنا وكيع قال: حدثنا أسامة بن زيد عن بعض أشياخه قال: قال عمر: إذا أراد أحد منكم أن يحسن الجارية فليزينها وليطوف بها يتعرض بها رزق الله > > 22791- Narrated by Waki: Usamah ibn Zaid narrated to us, from some of his elders, he said: Umar said, "If one of you intends to improve the condition of a slave girl, let him adorn her and take her around, for thereby Allah's sustenance may come." > > حدثنا أبو بكر قال: حدثنا وكيع، قال: حدثنا العلاء بن عبد الكريم، عن عمار بن عمران، رجل من زيد الله عن امرأة منهم، عن عائشة، أنها شوفت جارية وطافت بها وقالت: لعلنا نصيب بها بعض شباب قريش > > 22792- Narrated by Waki: Al-Ala ibn Abd al-Karim narrated to us, from Ammar ibn Imran, a man from Zaid Allah, from a woman among them, from Aisha: She observed a slave girl, walked around with her, and said, "Perhaps some young men from the Quraysh might be interested in her." > > — [Musannaf Ibn Abi Shaybah](https://ia802801.us.archive.org/31/items/WAQ63900/musnfsh07.pdf#page=591) Are these hadiths authentic? What justifies advertizing a girl to tempt men? why are the slave girls allowed to be adorned and is this wrong since the prophet (saw) said the worst of the women are those that show off their beauty?
