This verse indeed confirms that all humans will pass by Hell and see it, yet we immediately note an important use of words between this verse and other verses that speak of the disbeliever's entry into Hell.
In 19:71 the Arabic word (Waredha) is used, which means (pass by and see). However, in the verses that speak about the disbelievers entry into Hell, we note the word (Dokhool) is used which means (entering), as opposed to passing by:
"Your Lord says, "Implore Me, and I will respond to you. Surely, those who are too arrogant to worship Me will enter Hell, forcibly." 40:60
In spite of the believers passage through Hell, yet they will be shielded from its suffering, this is confirmed in the words:
"On the Day of Resurrection you will see the faces of those who lied about GOD covered with misery. Is Hell not the right retribution for the arrogant ones?
And GOD will save those who have maintained righteousness; He will reward them. No harm will touch them, nor will they have any grief." 39:60-61
This could be compared to someone travelling through the blistering heat of the open desert in an air-conditioned car. Although he is in the middle of the desert yet he is shielded from its heat and enjoying the cool air-conditioned drive.
Further confirmation of this meaning is indicated in the Quran in reference to the story of Abraham:
"They said, "Burn him and support your gods, if this is what you decide to do." We said, "O fire, be cool and safe for Abraham." 21:68-69
He we are told that although Abraham was literally thrown into the fire by his idolatrous countrymen, yet he was not harmed by it.
The wisdom to be attained from this event taking place on Judgment Day (the passage of the believers by Hell) is truly of great importance.
FIRST:
To the believers, upon their passing by Hell and seeing all the suffering within, they will indeed realise the great victory they have attained by avoiding Hell:
"Every person tastes death, then you receive your recompense on the Day of Resurrection. Whoever misses Hell, barely, and makes it to Paradise, has attained a great triumph." 3:185
SECOND:
Upon seeing Hell the believers are also assured that God's promise of Heaven and also of Hell were fulfilled. Again, this will make them praise Almighty God :
"They will say, "Praise be to GOD, who fulfilled His promise to us, and made us inherit the earth, enjoying Paradise as we please." What a beautiful recompense for the workers!" 39:73-74
