What is the ruling on exaggerating crowding and aligning in rows—including pressing the arm and heel against the adjacent foot—and is this action part of the Sunnah of the noble Companions, with a clarification of the ruling in the Maliki school of thought?

Initiating to be in the first row indicates a Muslim's eagerness for good and the strength of their faith, which is something encouraged by the Shariah. Moreover, establishing, straightening, and compacting the rows are among the Sunnahs of prayer according to the majority of scholars. However, there should be no exaggeration in compacting and crowding to the extent that the row is disrupted and some worshippers are pushed out of it, as this contradicts the orderliness and straightening of the rows.
