What is the ruling on displaying a deceased Muslim in the mosque, stretched out in his coffin with his face uncovered, for a final farewell gaze, in imitation of what non-Muslims do?

Kissing the deceased by someone who is permitted to do so is permissible, as it is established in the Sunnah. However, placing the deceased in the mosque to bid farewell is not supported by any religious text. It is an act that is not commanded by the religion and is rejected. It also involves imitating non-Muslims and contradicts the instruction to hasten the funeral.
