Be truthful with yourself and others at all times .

This hadith speaks about the power of truthfulness in achieving success and entering heaven. It was narrated by Malik b. Anas and Talha b. 'Ubaidullah, who both reported that the Prophet said that if someone is true to what they profess, they will succeed or enter heaven depending on their faithfulness to their words. This hadith emphasizes the importance of being honest with oneself and others in order for one's actions to be rewarded with success or entrance into paradise after death. It also serves as a reminder that lying has consequences which can prevent one from achieving their goals or entering paradise after death, so it is important for people to be truthful in all aspects of life in order for them to reap its rewards both now and later on in life when judgement day comes around.
