Do good deeds and strive to prepare for judgement day .

This hadith is about preparing for the Day of Judgement, which is when all people will be judged by Allah according to their deeds in this world. The Prophet Muhammad stood up one night and looked at the horizon, asking what treasures have been opened and what trials have occurred. He then warned people that many who are dressed in this world will be naked on the Day of Rising, meaning that they will not have any good deeds or rewards with them when they are judged by Allah. This hadith teaches us that we should always strive to do good deeds so that we can be rewarded on the Day of Judgement, and it also reminds us to take care in our actions as we do not know when our time may come.
