Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Companions of the Messenger of Allah (peace and blessings be upon him) complained to him (peace and blessings be upon him) of the strain they felt in prostration (from keeping their arms spread apart), so he (peace and blessings be upon him) said: "Seek help from your knees." Ibn Ajlan said: This means that when the prostration becomes long and one is supplicating, he should rest his elbows on his knees. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The worst thief among people is the one who steals from his prayer." The Companions said: O Messenger of Allah, how does he steal from his prayer? He said: "He does not complete its bowing and its prostrations." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. In my view, the reason for this is a disagreement over it between the scribe of al-Awza'i and al-Walid bin Muslim.

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, the worst thief among people is the one who steals from his prayer." It was said: O Messenger of Allah, how does he steal from his prayer? He said: "He does not complete its bowing and its prostrations." Both of these chains are sahih (authentic), but they did not record it.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) forbade a man, when sitting in the prayer, to lean on his left hand. In the narration of Ishaq: that a man lean on his hands in the prayer. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: It is from the Sunnah of the prayer that the tashahhud be recited quietly (in a low voice). This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. It has a supporting narration (shahid) with an authentic chain from Aishah:

Sayyidah Aishah (may Allah be pleased with her) says that this verse: "And do not recite your prayer too loudly, nor too quietly" [Al-Isra: 110] was revealed concerning the tashahhud.

It is narrated from Sayyiduna Fadalah bin Ubayd al-Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) saw a man who prayed but neither praised and glorified Allah nor sent blessings upon the Prophet (peace and blessings be upon him), and then left. So he (peace and blessings be upon him) said: "This man has been hasty." Then he (peace and blessings be upon him) called him and said to him and to others: "When one of you prays, let him begin with the praise and glorification of his Lord, then let him send blessings upon the Prophet (peace and blessings be upon him), and after that let him supplicate for whatever he wishes." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

Sayyidah Aishah (may Allah be pleased with her) narrates that the Prophet (peace and blessings be upon him) used to give only a single salam in the prayer, facing straight ahead, turning slightly towards the right side. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. Wuhayb bin Khalid narrated it from Ubaydullah bin Umar, from al-Qasim, from Aishah: that she used to give a single salam. And the two Shaykhs agreed on using Amr bin Abi Salamah and Zuhayr bin Muhammad as evidence.

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Hadhf in the salam (i.e. not drawing it out too long) is Sunnah." This hadith is sahih (authentic) on the condition of Muslim, for he cited Qurrah bin Abd al-Rahman as supporting evidence in two places in his book. Abdullah bin al-Mubarak narrated this hadith from al-Awza'i as a statement of the Companion (mawquf):

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him): Shortening (hadhf) the salam is Sunnah.
