Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Stand close together in the rows so that the 'awlad al-hadhaf' (young of the hadhaf) do not come in between you." I asked: "O Messenger of Allah, what are the 'awlad al-hadhaf'?" He (peace and blessings be upon him) said: "They are small, hairless, black sheep found in the land of Yemen." This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, but they did not record it with these words.

Sayyiduna Anas (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Straightening the rows is part of the excellence of the prayer." This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim; they both agreed only upon the wording that making the rows even is part of the completion of the prayer.

It is narrated from Sayyiduna al-Irbad bin Sariyah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to seek forgiveness three times for those in the first row and once for those in the second row. This hadith has an authentic chain (sahih al-isnad) in all its aspects, but the two Shaykhs left it because of a hidden defect ('illah) in the narration from Sayyiduna al-Irbad (may Allah be pleased with him), which has already been mentioned.

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When one of you goes out from his house towards the mosque, one of his feet records a good deed and the other erases a sin." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "When one of you performs ablution (wudu) well and then goes out for the prayer, with nothing but the prayer taking him to the mosque, his left foot keeps erasing his sins and his right foot keeps recording a good deed for him, until he enters the mosque." This hadith is sahih (authentic) and its narrators are truthful, but the two Shaykhs did not record it.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that it is the Sunnah that when you enter the mosque you put your right foot first, and when you go out you put your left foot first. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) encouraged the people to pray, and forbade them from leaving before he (peace and blessings be upon him) had finished the prayer. This hadith is sahih (authentic) on the condition of Imam Muslim, but they did not record it.

Abd al-Hamid bin Mahmud narrates: I was praying with Sayyiduna Anas bin Malik (may Allah be pleased with him), and the people pushed us (because of the crowd) to stand between the pillars. Sayyiduna Anas stepped back, and when we had finished praying he said: "We used to avoid this (praying between the pillars) in the time of the Messenger of Allah (peace and blessings be upon him)."

Sayyiduna Qurrah bin Iyas (may Allah be pleased with him) narrates: We used to be forbidden from praying between the pillars, and we would be firmly driven away from there. Both of these chains are sahih (authentic), but the two Shaykhs did not record anything on this topic.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) liked the Muhajirun and the Ansar to be close to him (in the first row) so that they could learn (the method of prayer and the religion) from him. This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, but they did not record it.
