Hadith 2268
Sayyiduna Abu Hurairah (may Allah be pleased with him) and Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrate: The Prophet (peace and blessings of Allah be upon him) saw phlegm stuck (on the wall) in the direction of the Qiblah, so he took a pebble and scraped it off with it. Then he said: No one should ever spit in the direction of the Qiblah, nor to his right side. He should spit to his left side or under his left foot.
