His father said: "So and so sent me to ask him how the Messenger of Allah ﷺ prayed for rain (Istisqa')." He said: 'The Messenger of Allah ﷺ went out beseeching and humble, (dressed) in a state of humility. He did not give a Khutbah like this Khutbah of yours, and he prayed two rak'ahs.'" (Using translation from Nasāʾī 1506)
عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ فِي الِاسْتِسْقَاءِ فَقَالَ «خَرَجَ رَسُولُ اللهِ ﷺ مُتَضَرِّعًا مُتَوَاضِعًا مُتَبَذِّلًا فَلَمْ يَخْطُبْ نَحْوَ خُطْبَتِكُمْ هَذِهِ وَصَلَّى رَكْعَتَيْنِ»
