30-48 (The author of the book narrated) my father - may God be pleased with him - narrated that Ahmad ibn Sa’d ibn Abdullah quoted on the authority of Ahmad ibn Muhammad ibn Isa, on the authority of Al-Hassan ibn Ali al-Washsha’
“I asked Abil Hassan Al-Ridha (s): ‘Can someone whose hand has been wounded and is covered with medication just perform his ablutions over the covered area?’ The Imam (s) replied, ‘Yes. He can wash over it. That would suffice.’”
