Samura b. Jundub reported Allah's Messenger ﷺ as saying: There would be among them those to whom the fire will reach up to their ankles and to some of them the fire would reach their knees and to some it would reach their waists and to some it would reach up to their collar-bones.
This hadith serves as a reminder for us all that we should strive our best not only to obey Allah's commands but also stay away from any kind of sinning so we can avoid being punished severely in the hereafter. We should also remember that no matter how small or big our sins may seem, they still count against us and can lead us towards severe punishments if we do not repent soon enough or take steps towards improving ourselves spiritually before it is too late.
