Narrator:Abu Dharr
وَحَدَّثَنَا عَاصِمُ بْنُ النَّضْرِ التَّيْمِيُّ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي نَعَامَةَ، عَنْ عَبْدِ اللَّهِ بْنِ الصَّامِتِ، عَنْ أَبِي ذَرٍّ، قَالَ قَالَ " كَيْفَ أَنْتُمْ - أَوْ قَالَ كَيْفَ أَنْتَ - إِذَا بَقِيتَ فِي قَوْمٍ يُؤَخِّرُونَ الصَّلاَةَ عَنْ وَقْتِهَا
فَصَلِّ الصَّلاَةَ لِوَقْتِهَا ثُمَّ إِنْ أُقِيمَتِ الصَّلاَةُ فَصَلِّ مَعَهُمْ فَإِنَّهَا زِيَادَةُ خَيْرٍ "
Abu Dharr reported:
(The Messenger of Allah) said: How would you, or how would thou, act if you survive to live among people who defer prayer beyond the (prescribed) time? (The narrator said: Allah and His Messenger know best). whereupon he said: Observe prayer at its prescribed time, but if the Iqama is pronounced for (congregational) prayer, then observe prayer along with them. for herein is an excess of virtue.
