i remember reading a hadith where the Prophet (pbuh) was sitting with his companions when all of a sudden they were made to hear a loud crash,
.....
One day when the companions were with the Prophet (pbuh) he heard the sound of something heavy crash,
he asked, "Do you know what that was?" To which they replied, "Allah, and His Messenger (pbuh) know best."
"That was a stone that had been thrown into Hell seventy years ago, it kept falling until that moment.
It reached the bottom of Hell just now and the sound you heard was when it hit the bottom."
just think bro/sis - seventy years of ups and downs on earth can't be that much of a long time when you consider that the person bound for hell will go through seventy years of scorching agony just to fall to the bottom - and eternity awaits.............
Narrated Sahl bin Sad As-Sa’idi: “The Messenger of Allah (may Allah bless him and grant him peace), and the kafirun faced each other and started fighting.
When the Messenger of Allah returned to his camp and when the kafirun returned to their camp,
someone talked about a man amongst the companions of the Messenger of Allah who had been pursuing and killing with his sword any kafir fleeing alone.
He said, ‘No- one fought as hard today as that man.’
The Messenger of Allah said, ‘Truly, he is one of the people of the Fire.’
A man among the people said, ‘I shall follow him (to see what he does).’ So he followed him, and wher-ever he stood, he would stand with him, and wherever he ran, he would run with him.
“Then the (brave) man was wounded seriously and decided to bring about his own death quickly.
He slanted the blade of the sword in the ground directing its sharp end towards his chest between his two breasts. Then he leaned on the sword and killed himself.
The other man came to the Messenger of Allah, may Allah bless him and grant him peace, and said, ‘I testify that you are the Messenger of Allah.’
The Prophet asked, ‘What happened?’
He replied, ‘(It is about) the man whom you described as being one of the people of the Fire. The people were greatly surprised at what you said, and so I said, “I will find out his reality for you.” So, I followed him and watched him.
He was severely wounded, and hastened to die by slanting the blade of his sword in the ground and directing its sharp end towards his chest between his two breasts. Then he leant on his sword and killed himself.’
“Then the Messenger of Allah, may Allah bless him and grant him peace, said, ‘A man may seem to the people as if he were practising the deeds of the people of Paradise while in fact he is from the people of the Fire,
and another may seem to the people as if he were practising the deeds of the people of Hell, while in fact he is from the people of the Garden.’”
(Sahih Al-Bukhari Volume 4, Book 52, Number 147).
