It was narrated that ‘Aishah said:“When the Messenger of Allah (ﷺ) came to a sick person, he would make supplication for him, and would say: Adhhibil-bas, Rabban-nas, washfi Antash-Shafi, la shifa’a illa shifa’uka shifa’an la yughadiru saqama (Take away the pain, O Lord of mankind, and grant healing, for You are the Healer, and there is no healing but Your healing that leaves no trace of sickness).’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي الضُّحَى، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ إِذَا أَتَى الْمَرِيضَ فَدَعَا لَهُ قَالَ “ أَذْهِبِ الْبَاسْ رَبَّ النَّاسْ وَاشْفِ أَنْتَ الشَّافِي لاَ شِفَاءَ إِلاَّ شِفَاؤُكَ شِفَاءً لاَ يُغَادِرُ سَقَمًا ” .
