Al-Imām al-Bukhārī narrates: ‘Alī narrated to us; he said: Sufyān narrated to us; he said: al-Zuhrī narrated to us from Sa’īd ibn al-Musayyib and from ‘Abbād ibn Tamīm,
from his uncle, who said: A man complained to the Messenger of Allāh ﷺ that he experiences a doubt during Salāh, thinking that something has happened (i.e. that wind has been released). The Prophet ﷺ said: “He should not leave the Salāh unless he hears a sound or finds a smell.”
