From Sahih Muslim (Hadith 6182):
Abu Huraira reported that Allah's Messenger (ﷺ) said:Who amongst you is fasting today? Abu Bakr said: I am. He (again) said: Who amongst you followed a funeral procession today? Abu Bakr said: I did. He (the Prophet) again said: Who amongst you served food to the needy? Abu Bakr said: I did. He (again) said: Who amongst you has today visited the sick? Abu Bakr said: I did. Thereupon Allah's Messenger (ﷺ) said: Anyone in whom (these good deeds) are combined will certainly enter paradise
