Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ عَمْرِو بْنِ دِينَارٍ قَالَ سَمِعْتُ جَابِرًا يُحَدِّثُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَطَبَ فَقَالَ إِذَا جَاءَ أَحَدُكُمْ وَقَدْ خَرَجَ الْإِمَامُ فَلْيُصَلِّ رَكْعَتَيْنِ.
English Translation
Muhammad ibn Ja'far told us, Shu'bah told us, from Amr ibn Dinar, who said: I heard Jabir narrate that the Prophet, peace and blessings be upon him, delivered a sermon and said: If one of you comes and the imam has already gone out to lead the prayer, let him pray two rak'ahs.
