Hazrat Saeed Bin Musayyab (Rahmatullahi alaih) was one of the greatest and most senior among the Taabi’een. He never missed a single Salaat with Jamaat in forty years.
During his last illness, someone asked him about a Hadith. At that time he was unable to lift himself due to weakness.
He said to the person: “Sit down, and put me too in the sitting position.”
Those present objected, saying that due to his illness he should remain lying down.
He said: “Let me sit. I have been asked about the speech of my beloved (i.e. Rasulullah – Sallallahu alaihi wasallam). How can I be lying down?”
