وَعَنْ عَمَّارِ بْنِ يَاسِرٍ رَضِيَ اَللَّهُ عَنْهُمَا
قَالَ: سَمِعْتُ رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «إِنَّ طُولَ صَلَاةِ اَلرَّجُلِ، وَقِصَرَ خُطْبَتِهِ مَئِنَّةٌ مِنْ فِقْهِهِ»
He heard the Messenger of Allah (sallallahu alayhi wa sallam) say: “The length of a man’s prayer and the shortness of his Khutbah (religious talk) are a sign of his understanding (of the religion).”.
