Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said:“Worship the Most Merciful, spread peace among yourselves, feed (others), and enter Paradise.”

(Imam Ibn Hibban, may Allah have mercy on him, says:) The statement of the Prophet (peace and blessings be upon him):“Worship the Most Merciful”consists of such words that, regarding the differences among the addressed, can be used for various categories, which we have mentioned earlier, along with this description. And the statement of the Prophet (peace and blessings be upon him):“Spread peace among yourselves”consists of such words that are applied generally, but it is not obligatory to use them in all situations. Because if a person uses them in all situations, and for every individual, then the matter will become a cause of hardship, and this will go beyond a person’s capacity, and in this case, it would become obligatory upon Muslims to reply to the greeting, because replying to the greeting is obligatory. So this will suffice, so the greeting that is initiated, for which there is no specification of obligation, it is appropriate that it should suffice. The statement of the Prophet (peace and blessings be upon him):“Feed (others).”This is such a command that acting upon it is recommended, and its purpose is to encourage (people) to attain reward.
