The prophet was reported to have visited Sa’ad bin Aby Wagq’ass once when he was ill while in Mecca and he asked that a doctor be brought to examine him. They brought Al Harith bin Kaladah who examined him and said: There is no harm with him, just cook some fenugreek with dates and let him eat them, Saad was reported to have done that and then healed.
Fenugreek relieves urine retention and works as a laxative. When it is placed on the erratic nail, it will heal it.
