لَا بَأْسَ طَهُورٌ إِنْ شَاءَ اللهُ
Translation 
When the Prophet (peace and blessings of Allah be upon him) would enter upon a sick person, he would say,
“No harm, may it (the sickness) be a purification (for you), if Allah wills.”
Note: The excellence of visiting the sick;
Ali Ibn Abu Talib related that he heard the Messenger of Allah (peace and blessings of Allah be upon him) say,
“If a man calls on his sick Muslim brother, it is as if he walks reaping the fruits of Paradise until he sits, and when he sits he is showered in mercy, and if this was in the morning, seventy thousand angels send prayers upon him until the evening, and if this was in the evening, seventy thousand angels send prayers upon him until the morning.”
