And the proof of that is as follows: the one who is in the right—the seeker of guidance and truth—presents himself (1) to whoever criticized him for the deed in question, either by courteously posing a question or by gently seeking clarification (2) regarding the shortcoming the critic observed or heard about. Should he discover that the matter is grounded in ijtihad, a considered opinion, or a sound proof, he is content with that and remains silent, never divulging the incident to others unless he can accompany his report with the very ijtihad, opinion, or proof he found, thereby closing any gap.
Such a person is a seeker of guidance, a loving and sincere well-wisher (3) who pursues the truth and seeks to straighten his teacher’s deviation by informing him and discreetly hinting at it (4), just as the teacher seeks to straighten him. One of the Rightly Guided Caliphs—his name escapes me—said, “If I become crooked, then straighten me” (5).
This is a binding duty between teacher and student: the teacher seeks to establish the proof (6) against himself so that he may be corrected by it; he even suspects his own soul at times and learns of his states through others, driven by his fairness, love of truth, and wariness of falsehood—exactly as the disciple seeks such correction from his shaykh to mend whatever is unsound in deeds and words.
