Hadith 1529
Ibn ‘Abbas said that the Prophet went in to visit a Bedouin Arab, and when he entered to visit a sick man he was accustomed to say, “No harm will come; it is a purification, if God will.” He repeated these words, and when the man replied, “Not at all; it is on the contrary a fever which is boiling in an old man and will cause him to visit the graves,” the Prophet said, “Very well, then.” Bukharl transmitted it.
وَعَنِ ابْنِ عَبَّاسٍ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَخَلَ عَلَى أَعْرَابِيٍّ يَعُودُهُ وَكَانَ إِذَا دَخَلَ عَلَى مَرِيضٍ يَعُودُهُ قَالَ: «لَا بَأْسَ طَهُورٌ إِنْ شَاءَ اللَّهُ» فَقَالَ لَهُ: «لَا بَأْسَ طَهُورٌ إِنْ شَاءَ اللَّهُ» . قَالَ: كَلَّا بَلْ حُمَّى تَفُورُ عَلَى شَيْخٍ كَبِيرٍ تزيره الْقُبُور. فَقَالَ: «فَنعم إِذن» . رَوَاهُ البُخَارِيّ
