Spitting in the mosque

Sayyiduna Abu Umamah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Spitting in the mosque is a bad deed, and burying it is a good deed."
Ahmad and al-Tabarani in al-Mu'jam al-Kabir recorded it, except that he worded it: "It is a sin, and its expiation is burying it." The narrators of Ahmad have been deemed trustworthy (muwaththaq).

Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) says: I heard the Prophet (peace and blessings be upon him) say: "When any of you spits in the mosque, he should conceal his spittle (in the soil) so that it does not touch the skin or the clothing of a believer and harm him."
Ahmad and Abu Ya'la recorded it; its narrators have been deemed trustworthy (muwaththaq).

Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Muhammad bin Abi Layla, about whom there is criticism.

Sayyiduna Hudhayfah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "When any of you spits in the mosque, he should not spit to his right; rather, he should spit to his left or beneath his foot."
Al-Bazzar recorded it, and its narrators are the narrators of the Sahih.

Sayyiduna Samurah bin Jundub (may Allah be pleased with him) says: the Prophet (peace and blessings be upon him) used to command them that when they were in prayer they should not squat on the tips of their feet, and he (peace and blessings be upon him) used to say that when someone needs to spit during prayer, he should not spit in front of him or to his right, but beneath his foot, and then rub it into the ground.
Al-Bazzar recorded it, and al-Tabarani recorded it in abridged form in al-Mu'jam al-Kabir; its chain contains a narrator, Yusuf bin Khalid al-Samti, who is da'if (weak).

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".

Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Ja'far bin al-Zubayr, who is extremely da'if (weak).

Sayyiduna Abu Umamah (may Allah be pleased with him) says: One day the Prophet (peace and blessings be upon him) stood and began the prayer, and he saw spittle in the direction of the qiblah. He took off his sandals, then walked over to it and scraped it off; he did this three times. When he had completed his prayer, he turned his face towards the people, praised and glorified Allah Almighty, and then said: "O people! When any one of you stands in prayer, he stands in a mighty place before a mighty Lord, and he asks for a mighty thing: success through Paradise and deliverance from Hell. So when any one of you stands for prayer, he stands before Allah Almighty, facing his Lord; his angel is on his right and his companion (qarin) is on his left. So let none of you ever spit in front of him or to his right; he should spit to his left or beneath his foot, then rub it, and rub it hard, for he is only rubbing the ear of Satan. By the One who sent me with the truth! If the veils between you and him were removed, or he were given permission to speak, he would complain of what he suffers from that."
Al-Tabarani recorded it in al-Mu'jam al-Kabir through the narration of Ubaydullah bin Zahr from Ali bin Yazid, and both of these narrators are da'if (weak).

Sayyiduna Abu Umamah (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "When the servant stands in prayer, Paradise is opened for him, the veils between him and his Lord are lifted, and the wide-eyed houris come before him, as long as he does not spit or blow his nose."
Al-Tabarani recorded it in al-Mu'jam al-Kabir by way of Tarif bin al-Salt from al-Hajjaj bin Abdullah bin Harim; I have not found anyone who has given a biography of either of them.

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) says: the Prophet (peace and blessings be upon him) commanded a man to lead the people in the Zuhr prayer. While leading the people in prayer, that man spat towards the qiblah. When the time of the Asr prayer came, the Prophet (peace and blessings be upon him) sent word to another man (to lead the prayer). The first man became fearful; he came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah! Has something been revealed about me?" the Prophet (peace and blessings be upon him) said: "No! But you spat in front of you while you were leading the people, and so you have harmed Allah Almighty and His angels."
Al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are thiqat (trustworthy).
