Ma'qil bin An-Nu‘man bin Muqarrin (RAA) narrated, ‘I witnessed (battles with) Allah’s Messenger and if he did not start fighting at the beginning of the day, he delayed the fighting till the sun had passed the meridian, and the wind blew and victory descended from Allah.” Related by Ahmad and the three Imams. Al-Hakim graded it as Sahih.

وَعَنْ مَعْقِلٍ; أَنَّ اَلنُّعْمَانَ بْنَ مُقَرِّنٍ قَالَ: { شَهِدْتُ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-إِذَا لَمْ يُقَاتِلْ أَوَّلَ اَلنَّهَارِ أَخَّرَ اَلْقِتَالِ حَتَّى تَزُولَ اَلشَّمْسُ, وَتَهُبَّ اَلرِّيَاحُ, وَيَنْزِلَ اَلنَّصْرُ } رَوَاهُ أَحْمَدُ وَالثَّلَاثَةُ, وَصَحَّحَهُ اَلْحَاكِمُ [1]‏ .‏ وَأَصْلُهُ فِي اَلْبُخَارِيِّ [2]‏ .‏
