The Ruling on Praying the Greeting of the Mosque Before the Sun Sets

He has another question, saying: I see some of the praying brothers when they enter the mosque for the Maghrib prayer and the sun is setting, they pray two rak'ahs. When I told them: It is not permissible to pray at this time because the sun is in this state setting between the horns of Satan, he said to me: It is the greeting of the mosque. Is it permissible for him to pray it or not?
Answer: If the Muslim enters the mosque during the 'Asr prayer to sit and wait for the Maghrib, the Sunnah for him is to pray two rak'ahs. This is the best and this is the correct of the scholars' opinions, due to the saying of the Prophet (peace and blessings be upon him) between the adhan and the iqamah. And so it is in every prayer that it is recommended to pray two rak'ahs between the adhan and the iqamah. Yes.
Except for the 'Asr, where the best is to pray four, except for the 'Asr, the best is to pray four rawatib before it. And if his entry is after the sunset, it is Sunnah to pray two rak'ahs, there is no disagreement in that. If it is after the sunset, he prays two rak'ahs as the greeting of the mosque and between the adhan and the iqamah. But the disagreement is if it is before the sunset, before it has set.
The presenter: How authentic is this statement: that the sun is setting between the horns of Satan?
The Shaykh: This came in the hadith .... between the horns of Satan, and it sets between the horns of Satan. I say: It came in the hadith that it rises between the horns of Satan and sets between the horns of Satan, and at that time the disbelievers prostrate to it, at that time the disbelievers prostrate to it and worship it and magnify it, the worshippers of the sun. We ask Allah for safety. Yes.
