Does the questioner's saying, "Very easy," when asked about an exam, and her saying, "Yes, I studied," when asked about studying, constitute a violation of the Prophet's (peace and blessings be upon him and his family) saying: "Seek help in achieving your needs through concealment"?

The Hadith: "Seek help in the fulfillment of your needs by being discreet" is authentic, and it is used when there is a fear of envy (hasad). If there is no fear of envy, then one should speak of Allah's blessings as a form of gratitude, not out of boastfulness. If the inquirer is trustworthy, the blessing should be mentioned to him along with praise to Allah for it. However, if envy is feared, then it is better to conceal the blessing and use allusions (ma'areed).
