وَعَنْ حَارِثَةَ بْنِ وَهْبٍ الْخُزَاعِيِّ قَالَ: صَلَّى بِنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَنَحْنُ أَكْثَرُ مَا كُنَّا قَطُّ وآمنه بمنا رَكْعَتَيْنِ
Haritha b. Wahb al-Khuza‘i said, “God’s Messenger led us in a prayer of two rak'as in Mina when we were more numerous and more secure than we had ever been before.” (Bukhari and Muslim.)
