What is the ruling on making a minbar and building mosques?

The Shaykh : This should have come before that, but perhaps there is another mosque, if Allah wills. First, my brother, it is not permissible to build structures and raise them. Second, we should, as much as we can, not go beyond the limit of what is prescribed for the minbar. It consists of wooden planks on which the preacher stands to be visible to the people. Why marble and this decorated square wood, and so on? I mean, many things, and very many. As came in the hadith, Allah is the Greatest . It is only that it should shade the people, protecting them from heat and cold, as came in Sahih al-Bukhari from 'Umar ibn al-Khattab (may Allah be pleased with him) when he expanded the Prophet's Mosque in his time. He said to the builder: "Shade the people from the heat and the cold, and do not make it red or yellow." I am content now, if I want to adhere to the 'Umaric Sunnah, which is undoubtedly the Prophetic Sunnah, to say that these curtains here are green and there are yellow. This is what 'Umar ibn al-Khattab avoided. He said: "Shade the people from the heat and the cold, and do not make it red or yellow." Everything in the mosque must be simple, simple, meaning plain. What do you call it? Plain. It is plain.
Nothing in the mosque must ever attract attention, as you heard from some of the hadiths we mentioned, such as the hadith of the Khumayseh, the hadith of the ram of Isma'il (peace be upon him), and the hadith of the churches in Abyssinia. From this, 'Umar said: Do not make it red or yellow. So the mosque is intended, or among its purposes, is to shelter people from heat and cold. I have no objection to using heating devices, and I have no objection to using devices to moderate the weather.
