Khalaf bin ‘Umar (rahimahullah) narrates:

I was once with Imaam Maalik bin Anas (rahimahullah) when ibn Abi Katheer (rahimahullah), the Qari of the people of Madinah Munawwarah, approached him and handed a piece of paper to him. On receiving the piece of paper, Imaam Maalim (rahimahullah) glanced at it and thereafter placed it beneath the musallah. When ibn Abi Katheer (rahimahullah) stood to leave, I also began to stand, but Imaam Maalik (rahimahullah) said to me, “O Khalaf! Sit, and hand me the piece of paper.”
