Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Spittle spat in the direction of the qiblah will be raised up again on the Day of Resurrection, and it will be on the face of the one who spat it."
Al-Bazzar recorded it; its chain contains a narrator, Asim bin Umar, whom Bukhari (may Allah have mercy on him) and a group declared da'if (weak). Ibn Hibban mentioned him in his book "al-Thiqat".
