"And when Moosaa (Moses) came at the time and place appointed by Us, and his Lord spoke to him, he said: "O my Lord! Show me (Yourself), that I may look upon You." Allaah said: "You cannot see Me, but look upon the mountain if it stands still in its place then you shall see Me." So when his Lord appeared to the mountain, He made it collapse to dust, and Moosaa (Moses) fell down unconscious, Then when he recovered his senses he said: "Glory be to You, I turn to You in repentance and I am the first of the believers."" [Al-A'raaf (7):143]

Narrated Abu Huraira:

The Prophet said, "The person who participates in (Holy battles) in Allah's cause and nothing compels him to do so except belief in Allah and His Apostles, will be recompensed by Allah either with a reward, or booty (if he survives) or will be admitted to Paradise (if he is killed in the battle as a martyr). Had I not found it difficult for my followers, then I would not remain behind any sariya going for Jihad and I would have loved to be martyred in Allah's cause and then made alive, and then martyred and then made alive, and then again martyred in His cause." [The Book of Faith Volume 1, Book 2, Hadeeth 35]
