Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: "Visiting the sick on the first day is Sunnah, and after that it is voluntary."
Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat, but in it he recorded these words: "Whatever is beyond that is voluntary."
Al-Bazzar also recorded it, but he recorded these words: "Whatever is more is supererogatory (nafl)." In one of their chains is Ali bin Urwah, who is da'if (weak) and matruk (abandoned), and in the other chain is al-Nadr Abu Umar, and the hadith he narrates is hasan (good).
