البيهقي:٥٣٣٨ – أَخْبَرَنَا أَبُو الْحَسَنِ مُحَمَّدُ بْنُ الْحُسَيْنِ الْعَلَوِيُّ أنبأ أَبُو حَامِدِ بْنُ الشَّرْقِيِّ ثنا مُحَمَّدُ بْنُ يَحْيَى ثنا عَبْدُ الصَّمَدِ بْنُ عَبْدِ الْوَارِثِ ثنا شُعْبَةُ عَنْ أَيُّوبَ وَبُدَيْلُ بْنُ مَيْسَرَةَ عَنْ أَبِي الْعَالِيَةِ عَنْ عَبْدِ اللهِ بْنِ الصَّامِتِ عَنْ أَبِي ذَرٍّ رَفَعَهُ قَالَ ضَرَبَ فَخِذِي وَقَالَ كَيْفَ أَنْتَ إِذَا بَقِيتَ فِي قَوْمٍ يُؤَخِّرُونَ الصَّلَاةَ عَنْ وَقْتِهَا؟ ثُمَّ قَالَ

صَلِّ الصَّلَاةَ لِوَقْتِهَا ثُمَّ اخْرُجْ فَإِنْ كُنْتَ فِي الْمَسْجِدِ فَأُقِيمَتِ الصَّلَاةُ فَصَلِّ مَعَهُمْ  

أَخْرَجَهُ مُسْلِمٌ فِي الصَّحِيحِ مِنْ حَدِيثِ شُعْبَةَ عَنْ بُدَيْلِ بْنِ مَيْسَرَةَ مُسْنَدًا
