حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، حَدَّثَنِي حَمْزَةُ الْعَائِذِيُّ، - رَجُلٌ مِنْ بَنِي ضَبَّةَ - قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا نَزَلَ مَنْزِلاً لَمْ يَرْتَحِلْ حَتَّى يُصَلِّيَ الظُّهْرَ فَقَالَ لَهُ رَجُلٌ وَإِنْ كَانَ بِنِصْفِ النَّهَارِ قَالَ وَإِنْ كَانَ بِنِصْفِ النَّهَارِ ‏.‏

Narrated Anas ibn Malik: When the Messenger of Allah (PBUH) halted at a certain place (while on a journey), he would not leave that place till he offered the noon prayer. A man said to him: Even if in the middle of the day? He replied: Even if in the middle of the day. Translation Not Available
