It was
narrated that ‘Abdullah bin Sarjis said:
“I saw the bald
forehead
of ‘Umar bin Khattab when he kissed the Black Stone and said:
‘I
am kissing you, although I know that you are only a stone and you
can
neither cause harm nor bring benefit. Had I not seen the Messenger
of
Allah (ﷺ) kissing you, I would not have kissed you.’”
