The sincere Muslims will be taken out form hell-fire By Mohammad Rafique Etesame
Allah's Messenger (ﷺ) said, "When the people of Paradise have entered Paradise, and the people of the Fire have entered the Fire, Allah will say. 'Take out (of the Fire) whoever has got faith equal to a mustard seed in his heart.'
They will come out, and by that time they would have burnt and became like coal, and then they will be thrown into the river of Al-Hayyat (life) and they will spring up just as a seed grows on the bank of a rainwater stream." The Prophet (ﷺ) said, "Don't you see that the germinating seed comes out yellow and twisted?" Sahih al-Bukhari 6560 Book 81, Hadith 149
Hera a question arises that, there are many Muslims who
never miss their prayers, but along with it, they do not miss any opportunity to transgress Allah's limits. Or, even worse, and there are those Muslims also who spend every second of their life to sin and violate Allah's laws. It is as if sins are their intimate friends until the moment they die. Can people like this enter jannah (Paradise)?
So, this is an authentic belief of Islam that a Muslim who commits a grave sin, is within Allah's Will. He will forgive that person if He Wills, and if not, then the person will be put into hellfire.
And those sinful Muslims who will be entered hellfire, they won't stay there forever. But they will be tortured proportional with the number of sins what they have committed. The more they have sinned, the longer they will spend time in hellfire.
After spending their time in hellfire and burning off their sins, they will be taken out from hell and put into jannah because they still have a spot of imaan in their hearts.
A hadith reveals that faith is between fear from Allah and having hope of His mercy. It means a faithful believer should fear Allah Almighty and be hopeful of His mercy and should not be despair of it.
Because if he fears Allah, he will not be a sinful one, and if he is hopeful of His mercy, he will not transgress of the limits of Allah. May Allah give us power to act upon all His commands, Amin.
