Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he said: "When any one of you is in prayer, he should not spit in front of him because his Lord is in front of him, and he should spit to his left or under his foot. If he does not find a place to spit, then he should spit into his garment or his shoe (and after the prayer) take it outside."
