“O you who believe! Be afraid of Allaah, and be with those who are true (in word and deeds).” [al-Tawbah 9:119]

Ibn Katheer (may Allaah have mercy on him) said (2/414): “It means: be truthful and adhere to truthfulness, and you will be among its people and will be saved from calamity, and this will make a way out for you from your problems.”

‘Abd-Allaah ibn Mas’ood (may Allaah be pleased with him) said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘You must be truthful, for truthfulness leads to righteousness and righteousness leads to Paradise. A man will keep speaking the truth and striving to speak the truth until he will be recorded with Allaah as a siddeeq (speaker of the truth). Beware of telling lies, for lying leads to immorality and immorality leads to Hellfire. A man will keep telling lies and striving to tell lies until he is recorded with Allaah as a liar.” (Reported by Muslim, 4721)

“Do not trouble yourselves about standards or ideals; but try to be faithful and natural: remember that there is no greatness, no beauty, which does not come from truth to your own knowledge of things; and keep on working, even if your work is not long remembered.”
