Jaabir bin Samura radiyallahu anhu reports, "I observed Rasoolullah sallallahu alaihe wasallam lean on a pillow which was on his left side".
Abu Bakrah radiyallahu anhu relates that, "Rasoolullah sallallahu alaihe wasallam once said, :
Must I show you a great sin, from among the greatest sins?" The sahaabah replied, "Yes O Rasoolullah sallallahu alaihe wasallam, do tell us." Rasoolullah sallallahu alaihe wasallam replied, "To ascribe a partner unto Allah. To disobey one's parents. To bare false witness, (or tell a lie). (The narrator is not sure which of the two Sayyidina Rasoolullah sallallahu alaihe wasallam had said). At that time Rasoolullah sallallahu alaihe wasallam was leaning on something. When he mentioned lies, he sat up, and because of its importance began to repeat it many times, till we began hoping that he would stop, and not repeat it so many times".
Abu Juhayafah radiyallahu anhu reports that:
"Rasulullah sallallahu alaihe wasallam said: 'I do not lean when I have meals.'"
Jaabir bin Samurah radiyallahu anhu says:
"I had seen Rasulullah sallallahu alaihe wasallam lean on a pillow."
