حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، أَخْبَرَنَا أَبُو عِمْرَانَ الْجَوْنِيُّ، عَنْ عَلْقَمَةَ بْنِ عَبْدِ اللَّهِ الْمُزَنِيِّ، عَنْ مَعْقِلِ بْنِ يَسَارٍ، أَنَّ النُّعْمَانَ، - يَعْنِي ابْنَ مُقَرِّنٍ - قَالَ شَهِدْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم إِذَا لَمْ يُقَاتِلْ مِنْ أَوَّلِ النَّهَارِ أَخَّرَ الْقِتَالَ حَتَّى تَزُولَ الشَّمْسُ وَتَهُبَّ الرِّيَاحُ وَيَنْزِلَ النَّصْرُ ‏.‏

Narrated An-Nu'man ibn Muqarrin: I was present at fighting along with the Messenger of Allah (PBUH), and when he did not fight at the beginning of the day, he waited till the sun had passed the meridian, the winds blew, and help came down. Translation Not Available
