It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he said: "Visiting the sick on the first day is Sunnah, and whatever visiting is after that is voluntary."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these two hadiths from al-Nadr bin Arabi except Ibn Ulathah, and Amr bin al-Husayn is alone in narrating them both."
