There is etiquette to be followed with regard to Jumu‘ah prayer, to which the Muslim should pay attention on this day. One aspect of this etiquette is to be quiet and listen attentively to the khatib during his khutbah. The Prophet (blessings and peace of Allah be upon him) drew attention to that in this hadith, as he said: If you say to your companion on Friday, ‘Listen!’ – advising someone else and urging him to listen to the khutbah when the imam is delivering the khutbah – then you have engaged in idle speech. The word translated here as idle speech refers to invalid and improper speech. What is meant is: you have done something invalid that is not right. This is a prohibition on all kinds of speech during the khutbah, even if it appears to be advising someone else and even if few words are used. This word – “Listen!” – is mentioned even though it is not regarded as lengthy speech, and it comes under the heading of enjoining what is right. Therefore if the Prophet (blessings and peace of Allah be upon him) disallowed it, then it is appropriate that anything else that may be regarded as lengthy talk, and in which there is no enjoining of what is right, is also not allowed. It was said that this prohibition on telling the other person not to talk applies only if the idle talk that is happening is temporary and will stop, either by itself or if the imam says something to the one who is speaking. But if there are some people who are chatting and are distracted by their talk, and it is not possible to listen to the khutbah except by silencing them, then you may gesture to the one who is speaking or engaging in idle talk with a gesture from which he will understand that he should be quiet. If the gesture is not effective, then you may say brief words, because the reason for which it is forbidden to say, “Listen!” is so that people will be able to hear the khutbah. This hadith contains a warning against not listening attentively to the khutbah and being distracted by other things. This highlights the importance of keeping quiet during the Friday khutbah and listening to the imam..
