Rules of Greeting in Prayers 6item Is it obligatory to respond to the greeting of children whether boys or girls? Is it obligatory to answer the person who greets another with the word "salām" instead of "salāmun alaykum"? If someone is greeted repeatedly with the salām, whether by one person or by many people at the same time, is it sufficient for him to reply once for all these greetings? A person was greeted with the salām but did not reply due to inattention or some other reason so that a short span of time passed, is it still obligatory for him to respond to it? What is your opinion with regards to answering a greeting that is not in the form of "al-salām ..."? A person enters upon a group of people and salutes them with the words "al-salāmu alaykum jamī‘an (peace be upon all of you)". If one of the people in the group is praying, is it obligatory for him to answer the salutation even though someone else in the group has already replied to the greeting?
