In essence, no man knows when and how he will die. Because death is a sure thing, the only secret that can not be known and suspected by humans. People who look healthy and young, it would not live long.
Imam Qurtubi in the Book of Allah Tadzkirah mentioned that the secret of this death angel Azrael has to make weep. The angel of death was even laughing and crying while revoking human lives.
Commentators prominent among Ahl Waljamaah tells dialogue between Allah SWT with angel Azrael.GOD Almighty once asked the angel Azrael, "Do you ever cry when you take the lives of children and grandchildren of Adam?"
Izril angel then replied, "I never laughed, never cried, and has also surprised and shocked."
"What makes you laugh?"
"When I was getting ready to take the lives of someone, I saw said to the shoemaker, 'Make the best possible shoes that can be worn for a year'. I laughed because the person has not had time to wear the shoes he had pulled out his life. "
Allah then asked another question, "What makes you cry?"
Angel Azrael replied, "I cried when unplugging the life of a pregnant woman in the middle of a barren desert, and will give birth. So I waited until the baby was born in the desert. Then I pulled her life crying because they hear the cries bayiya and no one knows it. "
"Then what makes you surprised and shocked?"
Angel Azrael replied, "I was surprised and shocked when they wanted to take the lives of one cleric thee. I saw a bright light came out of her room, every time I approached, the light was getting rid of the glare as. Then I pulled down his life with the light. "
Allah asked, "Do you know who he was?"
"Do not know, O God."
"Indeed, the man is the baby from the mother that you pull down his life in the arid desert, I am guarding him and not let him."
