Humility

It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him), and perhaps it is a marfu' hadith: The Prophet (peace and blessings be upon him) said: "Allah Almighty says: 'Whoever humbles himself for Me like this' (here the narrator Yazid turned his palm toward the ground and brought it close to the ground, and then narrated these words:) 'I raise him like this,' then he turned his palm toward the sky and raised both hands toward the sky."
Ahmad, al-Bazzar and al-Tabarani in al-Mu'jam al-Awsat recorded it, and his wording is: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said on the pulpit: "O people, adopt humility, for I heard the Prophet (peace and blessings be upon him) say: 'Whoever humbles himself for the sake of Allah Almighty, Allah Almighty grants him elevation and says: "Rise up (or stand upright)! May Allah Almighty keep you standing (or upright)." Such a person is great in the eyes of people and small in his own self. And whoever is arrogant, Allah Almighty cuts him down and says: "Be disgraced!" So he is small in the eyes of people while he considers himself great.'"
The narrators of Ahmad and of al-Bazzar are the narrators of the Sahih, and the chain of al-Tabarani contains a narrator, Sa'id bin Salam al-Attar, and he is a kadhdhab (liar).

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates this as a marfu' hadith up to the Prophet (peace and blessings be upon him): He (peace and blessings be upon him) said: "Whoever humbles himself for Me like this" (the narrator said this while pointing with his palm toward the ground), "I raise him like this" (the narrator pointed with his palm toward the sky).
Al-Tabarani recorded it in al-Mu'jam al-Saghir. Its chain contains a narrator, al-Husayn bin al-Muthanna, and I do not know him. The rest of its narrators are the narrators of the Sahih.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates this saying of the Prophet (peace and blessings be upon him): "In the head of every human being there is a bridle, which is in the hand of an angel. When he adopts humility, it is said to the angel: 'Raise his bridle,' and when he is arrogant, it is said to the angel: 'Lower his bridle.'"
Al-Tabarani recorded it, and its chain is hasan (good).

Sayyiduna Abu Umamah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Adopting humility is binding upon you, for humility is in the heart. Let no Muslim harm a Muslim, for sometimes a person wearing ordinary clothes is such that, if he were to swear an oath by the name of Allah, Allah Almighty would fulfil it."
Al-Tabarani recorded it. Its chain contains a narrator, Muhammad bin Sa'id al-Maslub, and he fabricates hadith.

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever humbles himself toward his Muslim brother, Allah Almighty grants him elevation, and whoever exalts himself over a Muslim, Allah Almighty brings him low."
Al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains a narrator, Abd al-Azim bin Habib, and he is da'if (weak).

It is narrated from him that the Prophet (peace and blessings be upon him) said: "There is no person but that in his head there is a bridle, and that bridle is in the hand of an angel. If he adopts humility, it is said to the angel: 'Raise the bridle.' And when that person wants to exalt himself (that is, does so out of arrogance), it is said to the angel: 'Lower the bridle' (the narrator has a doubt; perhaps the words are:) 'Lower his bridle.'"
Al-Bazzar recorded it, and its chain is hasan (good).

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "In the head of every human being there are two chains: one chain goes toward the sky and one chain goes toward the earth. When he adopts humility, Allah Almighty raises him by the chain that is toward the sky, and when that person is arrogant, Allah Almighty lowers him by the chain that is toward the earth."
Al-Bazzar recorded it. Its chain contains a narrator, Zam'ah bin Salih; most (scholars) have declared him da'if (weak). The rest of its narrators are thiqat (trustworthy).
