What is the ruling on lighting fires at the sacred sites?

The Shaykh : The scholars [stated that] lighting fires is specifically for Muzdalifah after returning from 'Arafah, whereas lighting fires in Mina or 'Arafah is a bid'ah (religious innovation). This practice involved them lighting fires or lamps or the like when they left 'Arafah. The Shaykh al-Islam said that this is a bid'ah. Lighting fires is for Muzdalifah so that people can identify their locations and find their way, because if the fires are in Muzdalifah, the reason for them is apparent, and that reason is the need for light. But in 'Arafah, there is no reason for it, so the one who adopts it does so as an act of worship. For this reason, we say it is a bid'ah. Likewise, regarding lighting fires in Mina, he says it is a bid'ah. However, in reality, lighting fires in Mina is needed at night. It appears that the Shaykh (may Allah have mercy on him) meant that perhaps when they left Mina on the Day of 'Arafah, they lit fires on the night when the people are in Muzdalifah. What does this imply? As for the nights in Mina—the night of the ninth, the night of the eleventh, the twelfth, and the thirteenth—people are in need of them. And this is what Faisal ibn Hamud al-Shamri says. Where is he? I do not see or hear him. Yes, very well.
