Continuation of the explanation of Abu Sa'id al-Khudri (may Allah be pleased with him), who said: I heard the Messenger of Allah (peace and blessings be upon him) say:

The Shaykh : He says: We say: "La" is a negation of the genus, and "salah" means, based on this assumption, both obligatory and voluntary prayer, and it includes prayer with bowing and prostration as well as what does not have bowing and prostration, such as the funeral prayer. And his saying: It is possible that the meaning is after the Fajr prayer, and it is possible that the meaning is after what? After the sun rises. But the narration of Muslim clarifies that the meaning is after the Fajr prayer. And therefore he said: Likewise, it also came in other hadiths besides the hadith of Abu Sa'id explicitly stating that the meaning is prayer, where he (peace and blessings be upon him) said, or rather the narrator said: And his saying: The meaning is until it rises completely, or until its first or second horn rises. But with that, as will come later, if Allah wills, the hadith of 'Uqbah that the prohibition extends until the sun rises the height of a spear. That is: after the 'Asr prayer. That is: its upper horn sets, meaning it sets completely. Agreed upon by al-Bukhari and Muslim. So if someone asks: What is the wisdom in that?
We say: The wisdom in this was indicated by the Prophet (peace and blessings be upon him and his family) And likewise at sunset, it sets between the two horns of Satan, and perhaps they prostrate to it in farewell. So they prostrate to it in greeting at its rising and in farewell at its setting. So we were prohibited from praying in these two times so that it not be a means to imitating them.
