Narrated Anas in another narration of the Hadith reported by Abu Dawud:
When [he (ﷺ)] traveled, and intended to pray a voluntary prayer, he used to direct his riding camel towards the Qiblah, say, "Allahu Akbar" and pray facing whatever direction it faced. [Its chain is Hasan (good)].
The Prophet (ﷺ) said: "The whole earth is a mosque (to pray on) except a graveyard and a toilet." [Reported by at-Tirmidhi and it has an 'Illa (a defect)].
وَعَنْ أَبِي سَعِيدٍ - رضى الله عنه - عَنْ اَلنَّبِيِّ - صلى الله عليه وسلم -{ اَلْأَرْضُ كُلُّهَا مَسْجِدٌ إِلَّا اَلْمَقْبَرَةَ وَالْحَمَّامَ } رَوَاهُ اَلتِّرْمِذِيُّ , وَلَهُ عِلَّةٌ . [1] .
Allah's Messenger (ﷺ) forbade prayer at seven places; a dump, a slaughter house, a graveyard, the middle of the path, a bathroom, and where camels sit at a watering place and on (roof) of the Ka'bah. [Reported by at-Tirmidhi who graded it Da'if (weak)].
Allah's Messenger (ﷺ) said: "When any of you comes to the mosque he should look and if he sees impurity on his sandals (shoes) he should wipe them and then pray in them." [Reported by Abu Dawud, and Ibn Khuzaimah graded it Sahih (authentic)].
وَعَنْ أَبِي سَعِيدٍ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِذَا جَاءَ أَحَدُكُمْ اَلْمَسْجِدَ , فَلْيَنْظُرْ, فَإِنْ رَأَى فِي نَعْلَيْهِ أَذًى أَوْ قَذَرًا فَلْيَمْسَحْهُ , وَلْيُصَلِّ فِيهِمَا } أَخْرَجَهُ أَبُو دَاوُدَ , وَصَحَّحَهُ اِبْنُ خُزَيْمَةَ [1]
Allah's Messenger (ﷺ) said: "If one of you steps on filth with his two leather socks then the earth is their purification." [Reported by Abu Dawud, and Ibn Hibban graded it Sahih (authentic)].
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِذَا وَطِئَ أَحَدُكُمْ اَلْأَذَى بِخُفَّيْهِ فَطَهُورُهُمَا اَلتُّرَابُ } أَخْرَجَهُ أَبُو دَاوُدَ وَصَحَّحَهُ اِبْنُ حِبَّانَ [1]
Allah's Messenger (ﷺ) said: "Talking is not befitting during the Salat (prayer), for it (prayer) consists only of glorifying Allah, declaring His Greatness and the recitation of the Qur'an." [Reported by Muslim].
وَعَنْ مُعَاوِيَةَ بْنِ اَلْحَكَمِ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِنَّ هَذِهِ اَلصَّلَاةَ لَا يَصْلُحُ فِيهَا شَيْءٌ مِنْ كَلَامِ اَلنَّاسِ , إِنَّمَا هُوَ اَلتَّسْبِيحُ , وَالتَّكْبِيرُ , وَقِرَاءَةُ اَلْقُرْآنِ } رَوَاهُ مُسْلِمٌ [1] .
We used to talk while engaged in Salat (prayer) during the lifetime of Allah's Messenger (ﷺ) and one would talk with his companion regarding his needs in prayer till (this verse) was revealed: "Guard strictly the prayers, especially the middle prayer; and stand before Allah with obedience," then we were commanded to observe silence (in prayer) and were forbidden to talk. [Agreed upon. This wording is from Muslim].
وَعَنْ زَيْدِ بْنِ أَرْقَمَ - رضى الله عنه - قَالَ : { إِنْ كُنَّا لَنَتَكَلَّمُ فِي اَلصَّلَاةِ عَلَى عَهْدِ اَلنَّبِيِّ - صلى الله عليه وسلم -يُكَلِّمُ أَحَدُنَا صَاحِبَهُ بِحَاجَتِهِ , حَتَّى نَزَلَتْ : (حَافِظُوا عَلَى اَلصَّلَوَاتِ وَالصَّلَاةِ اَلْوُسْطَى وَقُومُوا لِلَّهِ قَانِتِينَ) ]اَلْبَقَرَة : 238] , فَأُمِرْنَا بِالسُّكُوتِ , وَنُهِينَا عَنْ اَلْكَلَامِ } مُتَّفَقٌ عَلَيْهِ , وَاللَّفْظُ لِمُسْلِمٍ [1]
Allah's Messenger (ﷺ) said: "Glorification of Allah (i.e. saying) is for men and clapping of hands is for women." [Agreed upon].
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ اَلتَّسْبِيحُ لِلرِّجَالِ , وَالتَّصْفِيقُ لِلنِّسَاءِ } مُتَّفَقٌ عَلَيْهِ . [1] .
Narrated Mutarrif bin Abdullah bin Shikhkhir (RA) from his father, who said, "I saw Allah's Messenger (ﷺ) when he was engaged in prayer, and heard a sound from his chest, like the bubbling of a pot, from weeping." [Reported by al-Khamsah except Ibn Majah, and Ibn Hibban graded it Sahih (authentic)].
"I had the permission of Allah's Messenger (ﷺ) to see him in his house at two times, and whenever I entered to him while he was praying he would clear his throat as a sign to me." [Reported by an-Nasa'i and Ibn Majah].
وَعَنْ عَلَيٍّ - رضى الله عنه - قَالَ : { كَانَ لِي مَعَ رَسُولِ اَللَّهِ - صلى الله عليه وسلم -مَدْخَلَانِ , فَكُنْتُ إِذَا أَتَيْتُهُ وَهُوَ يُصَلِّي تَنَحْنَحَ لِي } رَوَاهُ النَّسَائِيُّ , وَابْنُ مَاجَهْ . [1]
I asked Bilal (RA), "How did you observe the Prophet (ﷺ) replying to their (the Companions) salutation while he was engaged in prayer?" He (Bilal) said: "He used to do this way," and he (Bilal) demonstrated by spreading his palm. [Reported by Abu Dawud and at-Tirmidhi. The latter graded it Sahih (authentic)].
Allah's Messenger (ﷺ) was (one time) offering prayer while he was carrying Umama, daughter of Zainab, when he prostrated he put her down and when he stood up he lifted her up. [Agreed upon].
وَعَنْ أَبِي قَتَادَةَ - رضى الله عنه - قَالَ : { كَانَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -يُصَلِّي وَهُوَ حَامِلٌ أُمَامَةَ بِنْتِ زَيْنَبَ , فَإِذَا سَجَدَ وَضَعَهَا , وَإِذَا قَامَ حَمَلَهَا } مُتَّفَقٌ عَلَيْهِ . [1]
"Allah's Messenger (ﷺ) said: "Kill the two black ones during Salat (prayer), the snake and the scorpion." [Reported by al-Arba'a, and Ibn Hibban graded it Sahih (authentic)].
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ اُقْتُلُوا اَلْأَسْوَدَيْنِ فِي اَلصَّلَاةِ : اَلْحَيَّةَ, وَالْعَقْرَبَ } أَخْرَجَهُ اَلْأَرْبَعَةُ , وَصَحَّحَهُ اِبْنُ حِبَّانَ [1] .
Allah's Messenger (ﷺ) said: "If the person who passes in front of another person in prayer knew the magnitude of his sin, it would have been better for him to wait for forty than pass in front of him." [Agreed upon. This wording is from al-Bukhari].
عَنْ أَبِي جُهَيْمِ بْنِ اَلْحَارِثِ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ لَوْ يَعْلَمُ اَلْمَارُّ بَيْنَ يَدَيِ اَلْمُصَلِّي مَاذَا عَلَيْهِ مِنْ اَلْإِثْمِ لَكَانَ أَنْ يَقِفَ أَرْبَعِينَ خَيْرًا لَهُ مِنْ أَنْ يَمُرَّ بَيْنَ يَدَيْهِ } مُتَّفَقٌ عَلَيْهِ , وَاللَّفْظُ لِلْبُخَارِيِّ . [1]
Allah's Messenger (ﷺ) was asked in the expedition of Tabuk about the Sutra of the person who is offering the prayer; he said , "It is (something) like the back of a saddle." [Reported by Muslim].
وَعَنْ عَائِشَةَ - رَضِيَ اَللَّهُ عَنْهَا- قَالَتْ : { سُئِلَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -- فِي غَزْوَةِ تَبُوكَ - عَنْ سُتْرَةِ اَلْمُصَلِّي . فَقَالَ : "مِثْلُ مُؤْخِرَةِ اَلرَّحْلِ } أَخْرَجَهُ مُسْلِمٌ . [1]
Allah's Messenger (ﷺ), "In case there is not before him (an object) like the back of a saddle, a Muslim's Salat (prayer) would be cut off by (the passing of) a woman, a donkey and a black dog." And it concludes: "the black dog is a devil." [Reported by Muslim].
وَعَنْ أَبِي ذَرٍّ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ يَقْطَعُ صَلَاةَ اَلْمَرْءِ اَلْمُسْلِمِ - إِذَا لَمْ يَكُنْ بَيْنَ يَدَيْهِ مِثْلُ مُؤْخِرَةِ اَلرَّحْلِ - اَلْمَرْأَةُ , وَالْحِمَارُ , وَالْكَلْبُ اَلْأَسْوَدُ . . . " اَلْحَدِيثَ . } وَفِيهِ { اَلْكَلْبُ اَلْأَسْوَدِ شَيْطَانٌ } . أَخْرَجَهُ مُسْلِمٌ [1] .
In another narration Abu Dawud and an-Nasa'i reported through Ibn Abbas (RA) a similar report without its end and connected the prohibition of a woman passing in front of a praying person to the state of being in her menstruation period.
Allah's Messenger (ﷺ) said: "If one of you prays towards an object separating him from the people and someone tries to pass (between him and the object) in front of him, let him turn him away but if he refuses he should fight him for he is a devil." [Agreed upon].
وَعَنْ أَبِي سَعِيدٍ اَلْخُدْرِيِّ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِذَا صَلَّى أَحَدُكُمْ إِلَى شَيْءٍ يَسْتُرُهُ مِنْ اَلنَّاسِ , فَأَرَادَ أَحَدٌ أَنْ يَجْتَازَ بَيْنَ يَدَيْهِ فَلْيَدْفَعْهُ , فَإِنْ أَبَى فَلْيُقَاتِلْهُ , فَإِنَّمَا هُوَ شَيْطَانٌ } مُتَّفَقٌ عَلَيْهِ .
