حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا حُسَيْنُ بْنُ عَلِيٍّ ، عَنْ زَائِدَةَ ، قَالَ : حَدَّثَنِي عَمْرُو بْنُ يَحْيَى الأَنْصَارِيُّ ، حَدَّثَنِي مُحَمَّدُ بْنُ يَحْيَى بْنِ حَبَّانَ ، عَنِ عَمْرِو بْنِ سُلَيْمِ بْنِ خَلْدَةَ الأَنْصَارِيِّ ، عَنْ أَبِي قَتَادَةَ صَاحِبِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " دَخَلْتُ الْمَسْجِدَ وَرَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، جَالِسٌ بَيْنَ ظَهْرَانَي النَّاسِ ، قَالَ : فَجَلَسْتُ ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : مَا مَنَعَكَ أَنْ تَرْكَعَ رَكْعَتَيْنِ قَبْلَ أَنْ تَجْلِسَ ؟ قَالَ : فَقُلْتُ : يَا رَسُولَ اللَّهِ ، رَأَيْتُكَ جَالِسًا ، وَالنَّاسُ جُلُوسٌ ، قَالَ : " فَإِذَا دَخَلَ أَحَدُكُمُ الْمَسْجِدَ ، فَلَا يَجْلِسْ حَتَّى يَرْكَعَ رَكْعَتَيْنِ " .
Abu Qatadah (RA)h (RA), a Companion of the Messenger of Allah (ﷺ) , said: I entered the mosque, when the Messenger of Allah (ﷺ) had been sitting among people, and I also sat down among them. Upon this the Messenger of Allah (ﷺ) said: What prevented you from offering two rak'ahs (of Nafl prayer) before sitting down? I said: Messenger of Allah, I saw you sitting and people sitting (around you and I, therefore, sat in your company). He (the Holy Prophet) then said: When anyone among you enters the mosque, he should not sit till he has observed two rak'ahs.
