Can you please provide commentary on the following Hadith:
Rasulullah (sallallahu ‘alayhi wa sallam) said: “There are four who will be judged by Allah on the Day of Qiyamah; A deaf person who cannot hear at all, an insane person, an old [senile] person and a man who [lived and] died in a period wherein there were no Prophets.
As for the deaf one, he will say: ‘Islam came and I did not hear a thing.’ The mentally challenged one will say: ‘Islam came and children were pelting me with dung.’ The senile person will say: ‘Islam came and I did not comprehend a thing.’ As for the one who died in between the sending of the Messengers, he will say: ‘No Messenger came to me.’
Then a covenant will be taken from them that they will surely obey Allah. Then a Messenger will be sent to them commanding them to enter Jahannam [to test their obedience to Allah]. By Him in whose Hand is the soul of Muhammad, if they enter it, they will not find it except cool and peaceful.'”
