Abu l-Aas (RA) reported that he said,“O Messenger of Allaah, the Shaytaan interrupts me when I pray, and I get confused in my recitation.” The Messenger of Allaah (peace and blessings of Allaah be upon him) said, “That is a shaytaan whose name is Khanzab. If you sense his presence, seek refuge with Allaah from him, and spit [dry spitting] towards your left three times.” [Abu’l-‘Aas] said: “I did that and Allaah took him away from me.”(Reported by Muslim, no. 2203)
