Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When any one of you performs ablution and goes to the mosque, and nothing motivates him except the prayer, he comes only for the prayer. Thus, when he enters the mosque, he remains in the state of prayer as long as the prayer keeps him detained. And as long as any one of you remains seated at his place of prayer, the angels continue to supplicate for him in these words «‏‏‏‏اللَّهُمَّ اغْفِرْ لَهُ، اللَّهُمَّ ارْحَمْهُ، اللَّهُمَّ تُبْ عَلَيْهِ، مَالَمْ يُؤْذِ فِيْهِ، وَمَا لَمْ یُحْدِثْ فِيْهِ» ‏‏‏‏: 'O Allah, forgive him. O Allah, have mercy on him. O Allah, accept his repentance,' as long as he does not harm anyone in the mosque and as long as he does not lose his ablution."

And the evidence that a single name may apply to two actions, one of which is commanded and the other forbidden under the same name «إِذِ اللَّهُ قَدْ أَمَرَنَا بِالسَّعْيِ إِلَى صَلَاةِ الْجُمُعَةِ، يُرِيدُ الْمُضِيَّ إِلَيْهَا، وَالرَّسُولُ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ الْمُصْطَفَى زَجَرَ عَنِ السَّعْيِ إِلَى الصَّلَاةِ، وَهُوَ الْعَجَلَةُ فِي الْمَشْيِ فَالسَّعْيُ الْمَأْمُورُ بِهِ فِي الْكِتَابِ إِلَى صَلَاةِ الْجُمُعَةِ غَيْرُ السَّعْيِ الَّذِي زَجَرَ عَنْهُ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ فِي إِتْيَانِ الصَّلَاةِ، وَهَذَا اسْمٌ وَاحِدٌ لِفِعْلَيْنِ، أَحَدُهُمَا فَرْضٌ، وَالْآخَرُ مَنْهِيٌّ عَنْهُ»

Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace be upon him) said: "When the prayer has been established, do not come running for the prayer, but come walking with calmness and dignity. Whatever part of the prayer you catch, perform it, and whatever part you miss, complete it."

It is narrated from Abu Sha’tha’ Muharibi, he says: We were in the mosque with Sayyiduna Abu Hurairah (may Allah be pleased with him), the muezzin gave the call to prayer, so a man stood up and went outside. Upon this, Sayyiduna Abu Hurairah (may Allah be pleased with him) said: As for this man, he has disobeyed Abul Qasim (peace and blessings be upon him). In the narration of Bundar, these words are present: This man has opposed the command of Abul Qasim (peace and blessings be upon him).

Sayyiduna Abu Mas’ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said:“The one who should lead the people in prayer is the one among them who recites the Qur’an the most. If they are equal in recitation of the Qur’an, then the one who knows the Sunnah of the Prophet more should lead. If they are equal in knowledge of the Sunnah, then the one who migrated earlier among them should lead, and if they are also equal in migration, then the oldest among them should lead.”This hadith is from Abu Mu’awiyah. In Shu’bah’s narration, the words are:“Their leadership in prayer should be by the one who recites Allah’s Book the most and is most knowledgeable, and the one who is foremost in recitation should lead.”In his narration, the words“the one who knows the Sunnah more should lead”are not present.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he said: "When there are three people, then one of them should lead them in prayer, and the one who has the most right to lead is the one who recites and knows the Qur'an the most among them."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) intended to dispatch an expedition, and it consisted of only a few people. The Messenger of Allah (peace and blessings be upon him) called them and asked:“How much of the Qur’an do you have memorized?”Then he listened to their recitation of the Qur’an, until he came to a young man among them and asked him:“O so-and-so, which surahs do you have memorized?”He replied:“I have memorized such-and-such surahs and Surah Al-Baqarah.”The Prophet (peace and blessings be upon him) asked:“You have memorized Surah Al-Baqarah as well?”He replied:“Yes.”Upon this, the Prophet (peace and blessings be upon him) said:“Go, you are their leader.”A man among them who was of honor and status said:“O Messenger of Allah, by the One whose attributes are such-and-such, I did not learn the Qur’an except out of fear that I would not be able to act upon it (that I would not be able to recite it in the night prayer).”The Messenger of Allah (peace and blessings be upon him) said:“Learn the Qur’an, recite it, and sleep as well. Indeed, the example of the Qur’an for the one who learns it, recites it, and stands in prayer with it at night is like a bag filled with musk whose fragrance spreads everywhere. And the one who learns the Qur’an, preserves it in his chest, and sleeps (does not recite it in the night prayer), his example is like a bag whose musk is tied shut (so its fragrance does not spread).”

Sayyiduna Malik bin Huwairith (may Allah be pleased with him) narrates that I and one of my companions came to the service of the Prophet (peace and blessings of Allah be upon him) (to learn religious matters). Then when we intended to return, the Prophet (peace and blessings of Allah be upon him) said to us: "When the time for prayer comes, give the adhan, then give the iqamah, then the elder among you should lead the prayer." In his narration, Al-Dawraqi has added these words: He says that I asked Hazrat Abu Qilabah: Why was proficiency in the recitation of the Qur'an not made the criterion? He replied that both companions were equal in recitation. (Therefore, the elder in age was given the right to lead the prayer.)

In this regard, the hadith of the Prophet (peace be upon him): "The one who is the best reciter of the Qur'an among them should lead the people in prayer," is evidence that a freed slave, if he is more proficient and skilled in reciting the Qur'an than a Qurayshi person, has a greater right to lead the prayer.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that when the Muhajirun arrived in Madinah Munawwarah, they settled on one side of Quba. When the time for prayer came, Sayyiduna Salim (may Allah be pleased with him), the freed slave of Sayyiduna Abu Hudhayfah (may Allah be pleased with him), led them in prayer, because he had memorized the most Qur'an among them. Among those Muhajirun were also such eminent Companions as Sayyiduna Umar bin Khattab and Abu Salamah bin Abd al-Asad (may Allah be pleased with them both). This hadith is from Ahmad bin Sinan.
