Ibn Abi Hatim has recorded some reports about the incident of its revelation: Sa`d said, "Four Ayat were revealed concerning me. A man from the Ansar once made some food and invited some Muhajirin and Ansar men to it, and we ate and drank until we became intoxicated. We then boasted about our status.'' Then a man held a camel's bone and injured Sa`d's nose, which was scarred ever since. This occurred before Al-Khamr was prohibited, and Allah later revealed,

﴿يَـأَيُّهَا الَّذِينَ ءَامَنُواْ لاَ تَقْرَبُواْ الصَّلَوةَ وَأَنتُمْ سُكَـرَى﴾

(O you who believe! Approach not AsSalat (the prayer) when you are in a drunken state). Muslim recorded this Hadith, and the collectors of the Sunan recorded it, with the exception of Ibn Majah. Another Reason Ibn Abi Hatim narrated that `Ali bin Abi Talib said, "Abdur-Rahman bin `Awf made some food to which he invited us and served some alcohol to drink. When we became intoxicated, and the time for prayer came, they asked someone to lead us in prayer. He recited `Say, `O disbelievers! I do not worship that which you worship, but we worship that which you worship ﴿refer to the correct wording of the Surah: 109﴾.''' Allah then revealed,

﴿يَـأَيُّهَا الَّذِينَ ءَامَنُواْ لاَ تَقْرَبُواْ الصَّلَوةَ وَأَنتُمْ سُكَـرَى حَتَّى تَعْلَمُواْ مَا تَقُولُونَ﴾

(O you who believe! Do not approach Salah when you are in a drunken state until you know what you are saying). '' This is the narration collected by Ibn Abi Hatim and At-Tirmidhi, who said "Hasan ﴿Gharib﴾ Sahih.'' Allah's statement,

﴿حَتَّى تَعْلَمُواْ مَا تَقُولُونَ﴾

(until you know what you are saying) is the best description for when one is intoxicated, that is, when he does not know the meaning of what he is saying. When a person is drunk, he makes obvious mistakes in the recitation and will not be able to be humble during the prayer. Imam Ahmad recorded that Anas said that the Messenger of Allah said,

«إِذَا نَعَسَ أَحَدُكُمْ وَهُوَ يُصَلِّي، فَلْيَنْصَرِفْ فَلْيَنَمْ، حَتَّى يَعْلَمَ مَا يَقُول»

(If one feels sleepy while he is praying, let him sleep for a while so that he knows the meaning of what he is saying.) This was also recorded by Al-Bukhari and An-Nasa'i. In some of the narrations of this Hadith, the Messenger said,

«فَلَعَلَّهُ يَذْهَبُ يَسْتَغْفِرُ فَيَسُبَّ نَفْسَه»

(...For he might want to ask for forgiveness, but instead curses himself!) Allah said,

﴿وَلاَ جُنُباً إِلاَّ عَابِرِى سَبِيلٍ حَتَّى تَغْتَسِلُواْ﴾

(nor while Junub (sexually impure), except while passing through, until you bathe (your entire body),) Ibn Abi Hatim recorded that Ibn `Abbas said that Allah's statement,

﴿وَلاَ جُنُباً إِلاَّ عَابِرِى سَبِيلٍ حَتَّى تَغْتَسِلُواْ﴾

(nor while Junub (sexually impure), except while passing through, until you bathe (your entire body,) means, "Do not enter the Masjid when you are Junub, unless you are just passing by, in which case, you pass through without sitting down.'' Ibn Abi Hatim said that similar is reported from `Abdullah bin Mas`ud, Anas, Abu `Ubaydah, Sa`id bin Al-Musayyib, Abu Ad-Duha, `Ata', Mujahid, Masruq, Ibrahim An-Nakha`i, Zayd bin Aslam, Abu Malik, `Amr bin Dinar, Al-Hakam bin `Utaybah, `Ikrimah, Al-Hasan Al-Basri, Yahya bin Sa`id Al-Ansari, Ibn Shihab and Qatadah. Ibn Jarir recorded that Yazid bin Abi Habib commented on Allah's statement,

﴿وَلاَ جُنُباً إِلاَّ عَابِرِى سَبِيلٍ﴾

(nor while Junub (sexually impure), except while passing through,) when some men from the Ansar, whose doors literally opened into the Masjid, were sexually impure, and they did not have water, their only way to get water was to pass through the Masjid. So, Allah sent down,

﴿وَلاَ جُنُباً إِلاَّ عَابِرِى سَبِيلٍ﴾

(nor while Junub (sexually impure), except while passing through,).'' What supports this statement by Yazid bin Abi Habib, may Allah have mercy upon him, is Al-Bukhari's report in his Sahih, that the Messenger of Allah said,

«سُدُّوا كُلَّ خَوْخَةٍ فِي الْمَسْجِدِ إِلَّا خَوْخَةَ أَبِي بَكْر»

(Close all the small doors in this Masjid, except that of Abu Bakr.) This is what the Prophet commanded at the end of his life, knowing that Abu Bakr will be the Khalifah after him, and that he would need to enter the Masjid on numerous occasions to manage the important affairs of the Muslims. Yet, the Messenger of Allah commanded that all the small doors that open into the Masjid be closed, except Abu Bakr's door. Some of the Sunan compilers recorded the Prophet saying that only `Ali's door should remain open, but this is an error, what is in the Sahih is what is correct. In his Sahih, Muslim recorded that `A'ishah said, "The Messenger of Allah said to me,

«نَاوِلِيِني الْخُمْرَةَ مِنَ الْمَسْجِد»

(Bring me the garment from the Masjid.) I said, `I am having my period.' He said,

«إِنَّ حَيْضَتَكِ لَيْسَتْ فِي يَدِك»

(Your period is not in your hand.) Muslim also collected a similar narration from Abu Hurayrah. This Hadith indicates that the woman is allowed to pass through the Masjid during menses or post-natal bleeding, and Allah knows best.
