حَدَّثَنَا الْقَعْنَبِيُّ، حَدَّثَنَا مَالِكٌ، عَنْ عَامِرِ بْنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، عَنْ عَمْرِو بْنِ سُلَيْمٍ الزُّرَقِيِّ، عَنْ أَبِي قَتَادَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِذَا جَاءَ أَحَدُكُمُ الْمَسْجِدَ فَلْيُصَلِّ سَجْدَتَيْنِ مِنْ قَبْلِ أَنْ يَجْلِسَ " .
Abu Qatadah reported the Messenger of Allah (May peace be upon him) as saying; when any one of you enters the mosque, he should pray two RAKAHS before sitting down.
