What is forbidden in prayer, such as laughing, looking around and the like

Sayyiduna Mu'adh bin Anas (may Allah be pleased with him) relates: The Prophet (peace and blessings be upon him) said: "The one who laughs during the prayer, the one who looks around, and the one who cracks his fingers all fall under one and the same ruling."
Ahmad and al-Tabarani in al-Mu'jam al-Kabir recorded it; its chain contains Ibn Lahi'ah, about whom there is criticism, and it is narrated from Zabban bin Fa'id, who is da'if (weak).

Sayyiduna Abu Hurayrah (may Allah be pleased with him) relates: My close friend (peace and blessings be upon him) enjoined three things upon me and forbade me three things. He forbade me from pecking like the pecking of a rooster, from squatting (iq'a') like the squatting of a dog, and from looking around like the looking around of a fox.
Ahmad, Abu Ya'la and al-Tabarani in al-Mu'jam al-Awsat recorded it, and Ahmad's chain is hasan (good).

Sayyiduna Jabir (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "When a man stands for prayer, Allah Almighty turns toward him. When that person looks around, Allah Almighty says: 'O son of Adam, toward whom are you looking? Is it someone who is better for you than Me? Stay turned toward Me.' When that person looks around a second time, Allah Almighty says the same again; and when that person looks around a third time, Allah Almighty turns His Face away from him."
Al-Bazzar recorded it; its chain contains al-Fadl bin Isa al-Raqashi, on whose weakness the hadith scholars are agreed.

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "When the servant stands for prayer (the narrator says: I think the words in the narration are:) he is before the Most Merciful. When he looks around, Allah Almighty says: 'Toward whom are you looking? Toward one better than Me? O son of Adam, stay turned toward Me, for I am better than everything toward which you look.'"
Al-Bazzar recorded it; its chain contains Ibrahim bin Yazid al-Khuzi, who is da'if (weak).

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "When one of you stands to perform the prayer, he should remain turned toward the prayer until he finishes it. Avoid looking around during the prayer, for as long as a man is in the state of prayer, he is speaking intimately with his Lord."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains al-Waqidi, who is da'if (weak).

Sayyiduna Abdullah bin Salam (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Do not look around during the prayer, for there is no prayer for the one who looks around."
Al-Tabarani recorded it in all three of his books. Its chain contains al-Salt bin Yahya, in al-Tabarani's narration in al-Mu'jam al-Kabir; al-Azdi declared him weak. In the narration of al-Mu'jam al-Saghir and al-Mu'jam al-Awsat there is a narrator al-Salt bin Thabit, and this is an error (wahm); this person is actually al-Salt bin Tarif. Imam al-Dhahabi mentioned him in Mizan al-I'tidal and cited this hadith under his entry. Imam al-Daraqutni (may Allah have mercy on him) says: There is idtirab (inconsistency) in the hadith he narrates. And Allah knows best.

Sayyiduna Abu Hurayrah (may Allah be pleased with him) relates: Previously, the Prophet (peace and blessings be upon him) used to turn to the right and left during the prayer. Then Allah Almighty revealed this verse: "Successful indeed are the believers, those who are humble in their prayer." After that, the Prophet (peace and blessings be upon him) remained in humility and did not turn to the right or left.
Al-Tabarani recorded it in al-Mu'jam al-Awsat and said: The narrator Hibarah bin Najm al-Iskandarani is alone in narrating it. (Allamah al-Haythami says:) I say: I have not found anyone who has given his biography, and the rest of the narrators of this narration are thiqat (trustworthy).

Sayyiduna Abu al-Darda' (may Allah be pleased with him) relates: I heard the Prophet (peace and blessings be upon him) saying: "Whoever performs ablution and does it well, then prays two rak'ahs and supplicates to his Lord, his supplication is answered, whether quickly or with some delay. And beware of looking around during the prayer, for there is no prayer for the one who looks around. If you are overcome, then do so in the voluntary prayer, but do not do so in the obligatory prayer."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains Ata' bin Ajlan, who is da'if (weak).

Sayyiduna Abu al-Darda' (may Allah be pleased with him) relates: I heard the Prophet (peace and blessings be upon him) saying: "Whoever stands for prayer and looks around, Allah Almighty rejects his prayer."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains Yusuf bin Atiyyah, who is da'if (weak).

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: Allah Almighty remains turned toward the servant as long as the servant does not look around, or a state of ritual impurity (hadath) does not befall him.
Al-Tabarani recorded it in al-Mu'jam al-Kabir. The narrator Abu Qilabah did not hear from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him).

Sayyiduna Khawwat bin Jubayr (may Allah be pleased with him) relates: I was praying when someone behind me said: Keep the prayer short, for we have a need of you. I turned around, and it was the Prophet (peace and blessings be upon him).
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains Abdullah bin Zayd bin Aslam, whom Yahya bin Ma'in and others declared weak, while Abu Hatim and Ma'n bin Isa declared him thiqah (trustworthy). Abu Dawud says: He is like his brother.
