Sheikh Mohamed El-Moctar El-Shinqiti, Director of the Islamic Center of South Plains, Lubbock, Texas, states the following: “Drawing the buraq is not a problem because we have the description in the hadith as “an animal with two wings, bigger than a donkey and smaller than a mule.” In sahih Al-Bukhari we read that `A’ishah (may Allah be pleased with her) had a toy of a horse with two wings. When the prophet (peace and blessings be upon him) saw it, he smiled and said: “a horse with two wings?!” And she said: “this is the horse of Sulaiman.” And then the Prophet (peace and blessings be upon him) smiled again.
as for the other things mentioned in the question such as the gate between lower heaven and second heaven, Al-Bayt Al-Ma`mur, Sidrat Al-Muntaha and the golden butterflies that come to sit on it from paradise for a children’s, I discourage you from drawing them for two reasons: 1) we lack the detailed description of these things in the hadiths of the Prophet (peace and blessings be upon him) and how each of them looks; 2) the sacredness of these objects requires that we stay away from trivializing them.”
