Allah's Messenger (ﷺ) said: "When one of you prays, he should put something in front of him, and if he cannot find something he should set up a stick; but if he has no stick with him he should draw a line, then what passes in front of him will not harm him." [Reported by Ahmad and Ibn Majah. And Ibn Hibban graded it Sahih (authentic). And he who claims it is Mudtarib (inconclusive) is not correct. Rather is Hasan (good)].
Allah's Messenger (ﷺ) said: "Nothing interrupts Salat (prayer), but avert as much as you can (things that cut off prayer)." [Reported by Abu Dawud and there is weakness in its chain].
وَعَنْ أَبِي سَعِيدٍ اَلْخُدْرِيِّ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ لَا يَقْطَعُ اَلصَّلَاةَ شَيْءٌ , وَادْرَأْ مَا اِسْتَطَعْتَ } أَخْرَجَهُ أَبُو دَاوُدَ , وَفِي سَنَدِهِ ضَعْفٌ . [1]
Allah's Messenger (ﷺ) forbade keeping one's hands on one's waist while praying. [Agreed upon]. The wording is that of Muslim's.
And it's meaning is to put (one's) hands on his waist.
عَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ : { نَهَى رَسُولُ اَللَّهِ - صلى الله عليه وسلم -أَنْ يُصَلِّيَ اَلرَّجُلُ مُخْتَصِرًا } مُتَّفَقٌ عَلَيْهِ , وَاللَّفْظُ لِمُسْلِمٍ . [1]
وَمَعْنَاهُ : أَنْ يَجْعَلَ يَدَهُ عَلَى خَاصِرَتِهِ [2]
Allah's Messenger (ﷺ) said: "If supper is brought (and the prayer is ready) start with it (the food) before you pray the Maghrib (prayer)." [Agreed upon].
وَعَنْ أَنَسٍ- رَضِيَ اَللَّهُ عَنْهُ- أَنَّ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -قَالَ : { إِذَا قُدِّمَ اَلْعَشَاءُ فَابْدَءُوا بِهِ قَبْلَ أَنْ تُصَلُّوا اَلْمَغْرِبَ } مُتَّفَقٌ عَلَيْهِ . [1]
Allah's Messenger (ﷺ) said: "When one of you is praying he must not remove pebbles (from his face) for the mercy is facing him." [Reported by al-Khamsah with a Sahih (authentic) chain].
وَعَنْ أَبِي ذَرٍّ - رضى الله عنه - [1] قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِذَا قَامَ أَحَدُكُمْ فِي اَلصَّلَاةِ فَلَا يَمْسَحِ اَلْحَصَى , فَإِنَّ اَلرَّحْمَةَ تُوَاجِهُهُ } رَوَاهُ اَلْخَمْسَةُ بِإِسْنَادٍ صَحِيحٍ [2]
I asked Allah's Messenger (ﷺ) about looking around during prayer and he said, "It is something which the devil snatches from a person's prayer." [Reported by al-Bukhari].
عَنْ عَائِشَةَ --رَضِيَ اَللَّهُ عَنْهَا-- قَالَتْ : { سَأَلْتُ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -عَنْ اَلِالْتِفَاتِ فِي اَلصَّلَاةِ ? فَقَالَ : "هُوَ اِخْتِلَاسٌ يَخْتَلِسُهُ اَلشَّيْطَانُ مِنْ صَلَاةِ اَلْعَبْدِ } رَوَاهُ اَلْبُخَارِيُّ . [1]
Allah's Messenger (ﷺ) said: "When anyone of you is engaged in Salat (prayer), he is holding intimate conversation with his Rabb so he should not spit in front of him, nor to his right side, but to his left side, under his foot". [Agreed upon].
وَعَنْ أَنَسٍ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِذَا كَانَ أَحَدُكُمْ فِي اَلصَّلَاةِ فَإِنَّهُ يُنَاجِي رَبَّهُ , فَلَا يَبْزُقَنَّ بَيْنَ يَدَيْهِ وَلَا عَنْ يَمِينِهِ , وَلَكِنْ عَنْ شِمَالِهِ تَحْتَ قَدَمِهِ } مُتَّفَقٌ عَلَيْهِ [1]
'Aishah (RA) had a Qiram (a soft piece of cloth with colours) with which she had screened one side of her house. The Prophet (ﷺ) said: "Take away this Qiram of yours, for its pictures are displayed in front of me during my prayer." [Reported by al-Bukhari].
وَعَنْهُ قَالَ : { كَانَ قِرَامٌ لِعَائِشَةَ -رَضِيَ اَللَّهُ عَنْهَا- سَتَرَتْ بِهِ جَانِبَ بَيْتِهَا فَقَالَ اَلنَّبِيُّ - صلى الله عليه وسلم -أَمِيطِي عَنَّا قِرَامَكِ هَذَا , فَإِنَّهُ لَا تَزَالُ تَصَاوِيرُهُ تَعْرِضُ لِي فِي صَلَاتِي } رَوَاهُ اَلْبُخَارِيُّ [1]
al-Bukhari and Muslim have also reported a Hadith narrated by her ['Aishah (RA)] in which is mentioned the story of Abu Jahm's Ambijania (a plain woolem garment) with the addition:
"it (the Khamisa) has distracted me from my prayer."
Allah's Messenger (ﷺ) said: "Those people who raise their eyes to heaven while in Salat (prayer) should stop (doing so) or else their sight will not return to them." [Reported by Muslim].
وَعَنْ جَابِرِ بْنِ سَمُرَةٍ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ لَيَنْتَهِيَنَّ قَوْمٌ يَرْفَعُونَ أَبْصَارَهُمْ إِلَى اَلسَّمَاءِ فِي اَلصَّلَاةِ أَوْ لَا تَرْجِعَ إِلَيْهِمْ } رَوَاهُ مُسْلِمٌ . [1]
Narrated 'Aishah (RA) in another narration of it from Muslim:
I heard Allah's Messenger (ﷺ) said: "No Salat (prayer) can be (rightly offered) with food brought (before the worshiper) or when he is resisting the urge to relive himself of the two filths (i.e. urine and feces)."
وَلَهُ : عَنْ عَائِشَةَ -رَضِيَ اَللَّهُ عَنْهَا- قَالَتْ : سَمِعْتُ رَسُولَ اَللَّهِ - صلى الله عليه وسلم -يَقُولُ : { لَا صَلَاةَ بِحَضْرَةِ طَعَامٍ , وَلَا هُوَ يُدَافِعُهُ الْأَخْبَثَانِ } [1]
Allah's Messenger (ﷺ) ordered that the mosques be built in residential districts and that it be cleaned and perfumed. [Reported by Ahmad, Abu Dawud, and at-Tirmidhi. The latter considered it Mursal [missing link in the chain after the Tabi'i (student of a Companion)].
عَنْ عَائِشَةَ -رَضِيَ اَللَّهُ عَنْهَا- قَالَتْ : { أَمَرَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -بِبِنَاءِ اَلْمَسَاجِدِ فِي اَلدُّورِ , وَأَنْ تُنَظَّفَ , وَتُطَيَّبَ. } رَوَاهُ أَحْمَدُ , وَأَبُو دَاوُدَ , وَاَلتِّرْمِذِيُّ , وَصَحَّحَ إِرْسَالَهُ . [1]
Narrated 'Aishah (RA) in al-Bukhari and Muslim [that Allah's Messenger (ﷺ) said], "When a pious person amongst them (the Jews and Christians) died they used to build a place of worship and prostration on his grave." In the same Hadith is:
Umar came over Hassan while reciting poetry inside the mosque and looked at him sternly, then he (Hassan) said: "I used to recite poetry inside it (the mosque) in the presence of one who is more pious than you [i.e. the Prophet (ﷺ)]". [Agreed upon].
وَعَنْهُ - رضى الله عنه - { أَنَّ عُمَرَ - رضى الله عنه - مُرَّ بِحَسَّانَ يَنْشُدُ فِي اَلْمَسْجِدِ , فَلَحَظَ إِلَيْهِ , فَقَالَ : "قَدْ كُنْتُ أَنْشُدُ , وَفِيهِ مَنْ هُوَ خَيْرٌ مِنْكَ } . مُتَّفَقٌ عَلَيْهِ . [1]
Allah's Messenger (ﷺ) said: "Whoever hears a man crying out in the mosque about something he has lost, he should say, 'May Allah not restore it to you', for the mosques were not built for this." [Reported by Muslim].
وَعَنْهُ قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ مَنْ سَمِعَ رَجُلاً يَنْشُدُ ضَالَّةً فِي اَلْمَسْجِدِ فَلْيَقُلْ : لَا رَدَّهَا اَللَّهُ عَلَيْكَ , فَإِنَّ اَلْمَسَاجِدَ لَمْ تُبْنَ لِهَذَا } رَوَاهُ مُسْلِم ٌ [1]
