Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) relates (the narrator said: I think he attributed it to the Prophet (peace and blessings be upon him)) that he (peace and blessings be upon him) said: "(When a man prays without a sutrah, then) a dog, a donkey, a woman who has reached puberty, a Jew, a Christian, a Magian and a pig (by passing in front) break his prayer; and if they pass at a distance farther than a stone's throw from you, the prayer will not be broken."
