Is the questioner sinful if she tells her irreligious friend that tests have proven her free of illness—contrary to the truth—for fear of revealing the secret of her illness, which she wishes to conceal even from her family?

The disobedient may be afflicted with illnesses and a difficult life as a punishment, so that he might repent, as confirmed by the Almighty's saying: "And whoever turns away from My remembrance - indeed, he will have a difficult life," and "And We will surely let them taste a minor torment before the greater torment that perhaps they will return." Calamities expiate sins. Affliction is treated with sincere repentance, seeking refuge in Allah through supplication, good deeds, and the company of people of faith. There is no harm in seeking medicine, for every disease has a cure, without despairing of Allah's mercy. It is recommended to perform Umrah and Hajj, drink Zamzam water, treat oneself with black seed and honey, and increase in charity.

Lying is forbidden except out of necessity or need, within the narrowest limits. It is permissible in some cases if it serves a benefit without harming others, such as reconciling between people, in war, or a man's conversation with his wife. It is permissible to use ma'areedh (allusions/double meanings) to avoid lying.

It is recommended to strive to guide female friends and to associate with people of goodness and righteousness.
