عَنِ ابْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا
قَالَ: «خَرَجَ اَلنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُتَوَاضِعًا، مُتَبَذِّلًا، مُتَخَشِّعًا، مُتَرَسِّلًا، مُتَضَرِّعًا، فَصَلَّى رَكْعَتَيْنِ، كَمَا يُصَلِّي فِي اَلْعِيدِ، لَمْ يَخْطُبْ خُطْبَتَكُمْ هَذِهِ»
The Messenger of Allah (sallallahu alayhi wa sallam) went out (of al-Madinah, to pray for rain) humbling (himself), wearing rough clothes, submissive, walking slowly, supplicating (Allah). Then, he offered two Rakat in the same way he prayed Eid, but did not deliver your kind of Khutbah (religious talk, sermon).
