A man said, "O Allah's Messenger (ﷺ)! Can the people of Paradise be known (differentiated) from the people
of the Fire; The Prophet (ﷺ) replied, "Yes." The man said, "Why do people (try to) do (good) deeds?" The
Prophet said, "Everyone will do the deeds for which he has been created to do or he will do those
deeds which will be made easy for him to do." (i.e. everybody will find easy to do such deeds as will
lead him to his destined place for which he has been created).
Sahih al-Bukhari Book 82, Hadith 3
