It was narrated from Sahl bin Mu’adh bin Anas that his father said: "The Messenger of Allah ﷺ said: 'Whoever steps over the people’s necks on Friday has built a bridge to Hell.’"
The Prophet Muhammad (peace be upon him) was teaching us about how our actions can lead us either towards Heaven or towards Hell. He wanted us to understand that even small acts of disrespect can have serious consequences in the afterlife if they are done consistently or with malicious intent. He was reminding us that even though some things may seem small or insignificant, they still matter in the eyes of Allah and can lead to dire consequences if done without thought or care for others around us.
