'Amr bin Al-'As (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "The difference between our observance of Saum (fasting) and that of the people of the Scriptures is Suhur (predawn meal in Ramadan)."

[Muslim].

وعن عمرو بن العاص رضي الله عنه أن رسول الله قال: "فصل ما بين صيامنا وصيام أهل الكتاب أكلة السحر. ((رواه مسلم)).
