Sayyiduna Abdullah bin Amr bin Al-As (may Allah be pleased with him) narrates from the Messenger of Allah (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Whoever performs ghusl on the day of Jumu'ah, then applies perfume from his wife's perfume if he has any perfume, and wears his best clothes, then (when he comes to the mosque) does not step over people's necks and does not engage in any idle activity during the sermon, then these actions will be an expiation for the sins committed between the two Fridays. And whoever engages in idle activity or steps over necks, he will receive the reward of the Zuhr prayer."
