Is overlooking the faults of others without hurting them in public considered showing consideration for others or being diplomatic, and what about the person who reveals shortcomings in front of others; is his action considered frankness or rudeness?

The believer is gentle, lenient, and compassionate, striving to reconcile interests and uphold the rights of Allah and His servants. He advises privately whenever possible, avoiding direct confrontation if it leads to embarrassment, following the Prophet's approach (peace be upon him): "What is wrong with people who do such and such?" If compelled to advise directly, he chooses the gentlest words and most appropriate times, clarifying that the advice stems from love and that "the believer is the mirror of his brother." Advising people publicly is blameworthy; it is closer to shaming than to counsel. Ibn Rajab quoted Al-Fudayl: "The believer conceals and advises, while the wicked exposes and shames."
