Musannaf Ibn Abi Shaybah 7649 — Those who disliked spitting towards

Sayyiduna Abu Sa'id (al-Khudri) (may Allah be pleased with him) said: "Once the Prophet (peace and blessings be upon him) entered the mosque with a palm stalk in his hand; he loved palm stalks. He saw spittle on the qiblah side and scraped it off. Then he turned to the people and said: 'O people! When one of you stands to pray, Allah, the Mighty and Majestic, faces him, and on his right there is an angel. Would any of you like a man to face him and spit in his face? So none of you should spit towards the qiblah or to his right. If one must spit, let him spit under his left foot or to his left. If he is in a hurry, let him spit into his garment.'"
