Anas (May Allah be pleased with him) reported

The Prophet (ﷺ) came to visit Sa'd bin 'Ubadah (May Allah be pleased with him) who presented bread and olive oil to him. The Prophet (ﷺ) ate it and said, "The observers of fast have broken their fast with you (this is the literal translation, but the meaning is: 'May Allah reward you for providing a fasting people with food to break their fast'); the pious people have eat your food and the angels invoked blessings on you."
