Surah Hud, Ayat 7

Ayat 7. And He it is Who has created the heavens and the earth in six Days and His Throne was on the water, that He might try you, which of you is the best in deeds. But if you were to say to them: "You shall indeed be raised up after death," those who disbelieve would be sure to say, "This is nothing but obvious magic. " 

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

[Muslim Book 006, Chapter 9, Hadith Number 2413].  

Lesson : We learn from this Hadith that Suhur is a distinctive mark with which Allah has blessed the Muslim Ummah.
