The Prophet ﷺ said, "Feed the hungry, visit the sick, and set free the captives."  

قَالَ رَسُولُ اللَّهِ ﷺ أَطْعِمُوا الْجَائِعَ وَعُودُوا الْمَرِيضَ وَفُكُّوا الْعَانِيَ  

Messenger of Allah ﷺ ordered us to do seven things and forbade us to do seven other things. He forbade us to wear gold rings, silk, Dibaj, Istabriq, Qissy, and Maithara; and ordered us to accompany funeral processions, visit the sick and greet everybody. (See Hadith No. 104)  

أَمَرَنَا رَسُولُ اللَّهِ ﷺ بِسَبْعٍ وَنَهَانَا عَنْ سَبْعٍ نَهَانَا عَنْ خَاتَمِ الذَّهَبِ وَلُبْسِ الْحَرِيرِ وَالدِّيبَاجِ وَالإِسْتَبْرَقِ وَعَنِ الْقَسِّيِّ وَالْمِيثَرَةِ وَأَمَرَنَا أَنْ نَتْبَعَ الْجَنَائِزَ وَنَعُودَ الْمَرِيضَ وَنُفْشِيَ السَّلاَمَ
