Just because they've invented the vaccine for covid-19 doesn't | Ilm4all
Just because they've invented the vaccine for covid-19 doesn't mean that you are immune from death. You still need to prepare for your Hereafter, and the best provision on your journey is to have Taqwa (being conscious of Allaah).
{And take a provision (with you) for the journey, but the best provision is Taqwa (piety, righteousness, etc.). So fear Me, O men of understanding!} [Surah al-Baqarah (2):197]
