[Machine] I entered with my father to the Messenger of Allah ﷺ, and my father saw someone on the back of the Messenger of Allah ﷺ. So he said, "Let me treat the person on your back, for I am a physician." The Messenger of Allah ﷺ said, "Are you a companion of his?" He said, "My son testifies with him." The Messenger of Allah ﷺ said, "Indeed, he does not benefit you, and you do not benefit him."
دَخَلْتُ مَعَ أَبِي عَلَى رَسُولِ اللهِ ﷺ فَرَأَى أَبِي الَّذِي بِظَهْرِ رَسُولِ اللهِ ﷺ فَقَالَ دَعْنِي أُعَالِجُ الَّذِي بِظَهْرِكَ فَإِنِّي طَبِيبٌ فَقَالَ أَنْتَ رَفِيقٌ قَالَ رَسُولُ اللهِ ﷺ مَنْ هَذَا مَعَكَ؟ قَالَ ابْنِي أَشْهَدُ بِهِ فَقَالَ أَمَا إِنَّهُ لَا يَجْنِي عَلَيْكَ وَلَا تَجْنِي عَلَيْهِ
