`Sayyiduna Abdullah bin Zaid Al-Ansari (may Allah be pleased with him) narrates that the condition of a person was mentioned before the Messenger of Allah (peace and blessings be upon him) who imagines that he feels something (i.e., wind) passing during prayer. So the Prophet (peace and blessings be upon him) said that he should not leave (the prayer) or turn away until he hears a sound or perceives a smell.
