It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) concerning this statement of Allah Almighty: "Those who are humble in their prayer" [Surah al-Mu'minun: 2] , that he said: "Humility (khushu') is in the heart, and it means that you keep your shoulders soft (in prayer) for your fellow Muslim, and that you do not look here and there in your prayer." The chain of narration of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) prayed, he would raise his gaze towards the sky. Then, when this verse was revealed: "Those who are humble in their prayer" [Surah al-Mu'minun: 2] , he (peace and blessings be upon him) lowered his head. This hadith would have been sahih (authentic) on the condition of the two Shaykhs, were it not for a disagreement (in the chain) concerning Muhammad bin Sirin, for it has also been reported from him as mursal; and the two Shaykhs did not record it.
