In this hadith, the Prophet (blessings and peace of Allah be upon him) explains which deeds of Islam are better than others, after believing and doing the pillars of Islam. That was in response to a question that someone asked. The Prophet (blessings and peace of Allah be upon him) mentioned two things: the first was frequently offering food to people, by which he meant more than what is required in zakah. That includes charity, gifts, hosting people, giving feasts and feeding the poor, seeking the pleasure of Allah (may He be exalted), because food is necessary for the maintenance of physical well-being, and the virtue of offering food to people increases at times when the need for it is greater, which is at times of famine and when prices are high. The second thing is saying salaam to every Muslim, seeking the pleasure of Allah, without differentiating between one person and another. That is because the greeting of Islam is for all Muslims, and the greeting of salaam is the first means of creating harmony and bringing about a sense of love among Muslims. Spreading the greeting of salaam enhances harmony and love among the Muslims and makes their slogan apparent and widespread, in contrast to other religious communities. In addition to that, it teaches self-discipline and humility, and shows respect to other Muslims. Offering food and spreading the greeting of salaam are mentioned together in this hadith because by means of both, one will show kindness in word and deed, which is the most perfect kindness. This is described as being the best of Islam after fulfilling the obligatory duties of Islam, because any Muslim who would offer food and spread the greeting of salaam would surely affirm his strong belief in Allah, His angels, His Books, His Messengers and the Last Day..
