The Book of Visiting the Sick
Supplication for the Sick
وَعَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اللَّه عَلَيْهِ وَسَلَّمَ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ ، دَخَلَ علي أعرأبي يَعُودُهُ وَكَانَ إِذَا دَخَلَ علي من يَعُودُهُ قَالَ: لاَ بَأْسَ، طَهُورٌ إِنْ شَاءَ اللَّهُ ((رَوَاهُ الْبُخَارِيّ)).
Ibn 'Abbas (May Allah be pleased with them) reported: The Prophet (ﷺ) visited a bedouin who was sick. Whenever he visited an ailing person, he would say, "La ba'sa, tahurun in sha' Allah [No harm, (it will be a) purification (from sins), if Allah wills]." [Al-Bukhari].
