A person was not sure whether he was in front of the imaam. What is the ruling?

Should a person stand to the right of the imaam if the row is full?

If a latecomer catches up with the imaam during rukoo’ (bowing)

What should be done if a third person joins two who are praying in jamaa’ah?

Ruling on praying alone behind a row in the congregation

Latecomer following another latecomer in prayer

When the intercom system fails and the sisters cannot see the imaam

Imaam does rukoo’ when a person has not finished al-Faatihah

Distance beyond which one does not have to attend congregational prayer in the mosque
