During the Time of Reckoning, every single person will have scriptures which are spread about. Therefore, every person will be in a state of confusion, wondering how to save himself in this great situation.
There is also another interpretation for this fleeing. The brother will flee from his brother because he had misguided him or had fallen short of the rights of brotherhood and had not carried out the due obligations towards him.
The son will flee from his father and mother because he had been negligent in his filial piety. The father and mother will flee from their children because they had been negligent in their upbringing. The husband will flee from his wife because he had neglected her rights, fed her from the unlawful or made her do acts of disobedience.
Therefore, the fleeing on this day will be a natural reaction, as it is the time for reckoning, requital and the reimbursement of rights to their owners. Human beings on this day will either be the creditors or the debtors.
