What About Praying Shoulder to Shoulder ?
Is it correct that the Prophet ﷺ ordered people to place their feet beside each other in the rows while praying or that neither the Tabi'een nor the Sahabah did this, they only prayed shoulder to shoulder, and they closed to gaps.
The best discussion I have seen on this topic is the booklet "Fiqh
al-Imaam" written in English by a Hanafi student and published in England.
