What is the ruling on straightening the rows and not leaving gaps for Satan, knowing that Satan is chained during the the month of Ramadan?

The hadith emphasizes the importance of straightening the rows, which is a Sunnah according to the majority of scholars. Straightening the rows means aligning them, ensuring those standing in them are in a straight line, standing shoulder to shoulder (taraṣṣ), completing the front rows first, filling gaps, and avoiding spaces. Many prophetic hadiths have indicated the command to straighten rows and fill gaps. The command is for recommendation (istihbab) as indicated by the Prophet's saying, "Indeed, straightening the row is part of the perfection of prayer."
