A man came to the Prophet ﷺ and asked, "Can you give me some short and concise advice?"
He ﷺ replied, "When you stand up to pray, then pray as if you are about to depart from this world. And never say anything that you will have to apologize for tomorrow. And stop desiring what is in other people's possessions"
- Reported by Aḥmad in his Musnad.
