The Ruling on Describing People as Happy or Unhappy

Question:
Therefore, the Shaykh informed us—may Allah protect you—that he explained the issue of the roots of creation in the previous lesson. What is the ruling on one who says, "May your right be happy, O so-and-so," or "May your right be happy, O so-and-so"?

Answer:
This falls under the category of optimism, may Allah protect you. This is a matter of optimism. As for saying "unlucky," it is not permissible for a person to despair of the mercy of Allah or to cause others to despair. Rather, he should make the hearts of his brothers feel at ease and not say to them, "You are wretched," or "You are unlucky," or "You are..." Even if they are afflicted with something they do not like, it is incumbent upon the Muslim to instill hope and good opinion of Allah, Glorified and Exalted is He, in their souls, and to advise them to repent and to hold themselves to account, for nothing befalls them except because of their sins. As for saying, "You are wretched" or "You are unlucky," this is not permissible. Yes, and Allah the Exalted knows best, and may Allah send prayers and blessings upon our Prophet Muhammad and upon his family and his Companions.
