The ruling on wearing a face covering in prayer and leaning against a wall or pillar

Q: Is it permissible to wear a face covering in prayer? Or to lean against a wall or pillar or the like?

A: Wearing a face covering in prayer is disliked except for a medical condition, and it is not permissible to lean against a wall or pillar in the obligatory prayer; because it is obligatory for the one who is able to stand upright without leaning. As for the voluntary prayer, there is no harm in that; because it is permissible to perform it while sitting, and performing it while standing is better than sitting.
