Strive to do good deeds in order to receive Allah's mercy on the Day of Judgment. Respect others' beliefs and practices.

This hadith speaks about the Day of Resurrection, when Allah will judge all people according to their deeds. It is said that those who were last in terms of coming after other nations will be the first to be judged on this day. This means that even though some people may have come later than others, they still have a chance at being rewarded for their good deeds and faithfulness. The hadith also mentions that Jews observe one day and Christians another day; this could mean that each nation has its own set of beliefs and practices which are respected by Allah on the Day of Judgment. Ultimately, it is important for us to remember that we should strive to do good deeds in order to receive Allah's mercy on this day.
