What did the Prophet Muhammad (saw) say about spitting while one is praying?
 Abdullah b. Umar reported:                      The Messenger of Allah (may peace be upon him) saw spittle on the wall towards Qibla, and scratched it away and then turning to the people said: When any one of you prays, he must not spit in front of him, for Allah is in front of him when he is engaged in prayer.
