The Messenger of Allah (ﷺ) commanded us to do seven things: to visit the sick, to follow the funeral (of a dead believer), to invoke the Mercy of Allah upon one who sneezes (i.e., by saying to him: Yarhamuk- Allah), to support the weak, to help the oppressed, to promote the greeting of 'As-Salamu 'Alaikum', and to help those who swear to do something to keep their oaths.[Al-Bukhari and Muslim].
