أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، وَمُحَمَّدُ بْنُ إِبْرَاهِيمَ بْنِ صُدْرَانَ، - وَاللَّفْظُ لَهُ - عَنْ خَالِدِ بْنِ الْحَارِثِ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ بُدَيْلٍ، قَالَ سَمِعْتُ أَبَا الْعَالِيَةِ، يُحَدِّثُ عَنْ عَبْدِ اللَّهِ بْنِ الصَّامِتِ، عَنْ أَبِي ذَرٍّ، قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم وَضَرَبَ فَخِذِي ‏"‏ كَيْفَ أَنْتَ إِذَا بَقِيتَ فِي قَوْمٍ يُؤَخِّرُونَ الصَّلاَةَ عَنْ وَقْتِهَا ‏"‏ ‏.‏ قَالَ مَا تَأْمُرُ قَالَ ‏"‏ صَلِّ الصَّلاَةَ لِوَقْتِهَا ثُمَّ اذْهَبْ لِحَاجَتِكَ فَإِنْ أُقِيمَتِ الصَّلاَةُ وَأَنْتَ فِي الْمَسْجِدِ فَصَلِّ ‏"‏ ‏.‏

It was narrated that Ahu Dharr said: "The Messenger of Allah (PBUH) said to me, and struck my thigh: 'What will you do if you stay among people who delay the prayer until its time is over?' He said: 'What do you command me to do?' He said: 'Offer the prayer on time, then go about your business. Then if the Iqamah for that prayer is saidand you are in the Masjid, then pray.'"
