*First Hadīth Of The Day*

حَدَّثَنَا  مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ أَبِي حَازِمٍ، عَنْ  سَهْلِ بْنِ سَعْدٍ ـ رضى الله عنه ـ قَالَ كَانَ النَّاسُ يُصَلُّونَ  مَعَ النَّبِيِّ صلى الله عليه وسلم وَهُمْ عَاقِدُو أُزْرِهِمْ مِنَ  الصِّغَرِ عَلَى رِقَابِهِمْ، فَقِيلَ لِلنِّسَاءِ ‏"‏ لاَ تَرْفَعْنَ رُءُوسَكُنَّ حَتَّى يَسْتَوِيَ الرِّجَالُ جُلُوسًا ‏"
‏‏.‏
 Narrated Sahl bin Sa`d:                       
The people used to offer the prayer with the Prophet (ﷺ) with their waist-sheets tied round their necks  because of the shortness of the sheets and the women were ordered not to lift their heads till the men  had sat straight.

*Second Hadīth Of The Day*

حَدَّثَنَا  عَبْدُ اللَّهِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا ابْنُ فُضَيْلٍ، عَنِ  الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ،  قَالَ كُنْتُ أُسَلِّمُ عَلَى النَّبِيِّ صلى الله عليه وسلم وَهُوَ فِي  الصَّلاَةِ فَيَرُدُّ عَلَىَّ، فَلَمَّا رَجَعْنَا سَلَّمْتُ عَلَيْهِ  فَلَمْ يَرُدَّ عَلَىَّ وَقَالَ ‏"‏ إِنَّ فِي الصَّلاَةِ شُغْلاً ‏"
‏‏.‏
 Narrated `Abdullah:                       
I used to greet the Prophet (ﷺ) while he was in prayer and he would return my greeting, but when we  returned (from Ethiopia) I greeted the Prophet (while he was praying) but he did not return the  greeting, and (after finishing the prayer) he said, "In the prayer one is occupied (with a more serious  matter)."

*Third Hadīth Of The Day*

حَدَّثَنَا  أَبُو مَعْمَرٍ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا كَثِيرُ بْنُ  شِنْظِيرٍ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ، عَنْ جَابِرِ بْنِ عَبْدِ  اللَّهِ ـ رضى الله عنهما ـ قَالَ بَعَثَنِي رَسُولُ اللَّهِ صلى الله عليه  وسلم فِي حَاجَةٍ لَهُ فَانْطَلَقْتُ، ثُمَّ رَجَعْتُ وَقَدْ قَضَيْتُهَا،  فَأَتَيْتُ النَّبِيَّ صلى الله عليه وسلم فَسَلَّمْتُ عَلَيْهِ، فَلَمْ  يَرُدَّ عَلَىَّ، فَوَقَعَ فِي قَلْبِي مَا اللَّهُ أَعْلَمُ بِهِ فَقُلْتُ  فِي نَفْسِي لَعَلَّ رَسُولَ اللَّهِ صلى الله عليه وسلم وَجَدَ عَلَىَّ  أَنِّي أَبْطَأْتُ عَلَيْهِ، ثُمَّ سَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ  عَلَىَّ، فَوَقَعَ فِي قَلْبِي أَشَدُّ مِنَ الْمَرَّةِ الأُولَى، ثُمَّ  سَلَّمْتُ عَلَيْهِ فَرَدَّ عَلَىَّ فَقَالَ ‏"‏ إِنَّمَا مَنَعَنِي أَنْ أَرُدَّ عَلَيْكَ أَنِّي كُنْتُ أُصَلِّي ‏"
‏‏.‏ وَكَانَ عَلَى رَاحِلَتِهِ مُتَوَجِّهًا إِلَى غَيْرِ الْقِبْلَةِ‏.‏

 Narrated Jabir bin `Abdullah:                       
Allah's Messenger (ﷺ) sent me for some job and when I had finished it I returned and came to the Prophet (ﷺ)  and greeted him but he did not return my greeting. So I felt so sorry that only Allah knows it and I  said to myself,, 'Perhaps Allah's Messenger (ﷺ) is angry because I did not come quickly, then again I greeted  him but he did not reply. I felt even more sorry than I did the first time. Again I greeted him and he  returned the greeting and said, "The thing which prevented me from returning the greeting was that I  was praying." And at that time he was on his Rahila and his face was not towards the Qibla.
