Where is the chair placed in the row during congregational prayer?

Question:
He says: I would like Shaykh Salih (may Allah preserve him), and we are making du'a for him, to offer advice to those who pray on chairs. Honorable Shaykh, some of them move ahead of the imam and some fall behind. What is the guidance on this matter?

Answer:
If they need to pray on chairs, there is nothing wrong with it. Allah the Exalted said: But do not make the chairs bulky and large in size such that they take up space in the row that is not needed and also inconvenience the worshippers. The chair should be as light as possible. There are light and compact chairs available for them to use. It is observed that they bring large chairs or wooden ones, which is unnecessary and inconveniences the worshippers. As for moving ahead, he should try to be in line with the row as much as possible.
