It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) was praying when a goat began to pass in front of him. He (peace and blessings be upon him) moved forward towards the qiblah until he pressed his stomach against the qiblah (wall) (so that it would pass behind him). This hadith is sahih (authentic) on the condition of Bukhari, but the two Shaykhs did not record it.
