The Messenger of Allaah (sallallaahu alayhi wasallam) said:

Worship al-Rahman, feed food [to others] and spread (the salutation) of al-salaam and you will enter Paradise.

Note: From the taqwa of Allaah, after tawhid (singling out Allaah with worship) is the creating of bonding and nearness through feeding food to others and spreading the salutation of salaam between each other.
