Strive towards righteousness, Do good deeds instead of bad ones.

This hadith is about the punishment that awaits those who have committed sins on the day of judgement. According to this hadith, if someone has done something wrong or sinful in their life, they will be held accountable for it on the day of judgement and they will be punished accordingly. The punishment mentioned here is that they will drink poison and live in Hell-fire eternally. This serves as a reminder to us all to stay away from sinning and strive towards righteousness so that we can avoid such punishments in the hereafter. We should also remember that Allah is All Knowing and He knows our every action so we should always strive to do good deeds instead of bad ones.
