I was present at fighting along with the Messenger of Allah ﷺ, 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.  

شَهِدْتُ رَسُولَ اللَّهِ ﷺ إِذَا لَمْ يُقَاتِلْ مِنْ أَوَّلِ النَّهَارِ أَخَّرَ الْقِتَالَ حَتَّى تَزُولَ الشَّمْسُ وَتَهُبَّ الرِّيَاحُ وَيَنْزِلَ النَّصْرُ
