حَدَّثَنَا عُبَيْدٌ، قَالَ: حَدَّثَنَا يُونُسُ بْنُ بُكَيْرٍ، قَالَ: حَدَّثَنَا خَالِدُ بْنُ دِينَارٍ أَبُو خَلْدَةَ قَالَ: سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، وَهُوَ مَعَ الْحَكَمِ أَمِيرٌ بِالْبَصْرَةِ عَلَى السَّرِيرِ
يَقُولُ: «كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِذَا كَانَ الْحَرُّ أَبْرَدَ بِالصَّلَاةِ، وَإِذَا كَانَ الْبَرْدُ بَكَّرَ بِالصَّلاةِ»
