The Prophet (saw) said, If you say to your companions: 'Be quiet' on a friday while the Imam is delivering the sermon, you have engaged in Laghw (idle talk or behaviour).

Only that believer is graced with the blessings and benefits of Friday, who looks forward for it most anxiously and eagerly; and wretched is the negligent one who is least interested in it and who does not even know in the morning which day has dawned.

O you who believe! when the call is made for prayer on Friday, then hasten to the remembrance of Allah and leave off trading; that is better for you, if you know.
