Abdullāh ibn ‘Abbās (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) visited a Bedouin while he was sick, and whenever he visited a sick person he would say: ""No harm, (it will be) purification (from sins) if Allah wills. [Al-Bukhari]

"عن عبدالله بن عباس -رضي الله عنهما- أنّ النبي -صلى الله عليه وسلم- دخلَ على أعرابيٍّ يَعُودُه، وكان إذا دَخَلَ على مَن يَعودُه، قال: «لا بأس؛ طَهُور إن شاء الله». [صحيح.] - [رواه البخاري.] "
