Whoever Swears By Other Than Allah, HE HAS COMMITTED SHIRK
Sa'd bin 'Ubaidah (رضى الله عنه) narrated that Ibn 'Umar (رضى الله عنهم) heard a man saying: "No by the Ka'bah." So Ibn 'Umar (رضى الله عنهم) said: "Nothing is sworn by other than Allah, for I heard the Messenger of Allah (ﷺ) say:
"Whoever swears by (something) other than Allah, he has committed disbelief (kufr) or Shirk."
