I heard the Messenger of Allah ﷺ say, when he was in ‘Aqiq: “Someone came to me from my Lord and said: ‘Pray in this blessed valley and say: (I intend to do) ‘Umrah in Hajj.’”
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ وَهُوَ بِالْعَقِيقِ أَتَانِي آتٍ مِنْ رَبِّي فَقَالَ صَلِّ فِي هَذَا الْوَادِي الْمُبَارَكِ وَقُلْ عُمْرَةٌ فِي حَجَّةٍ وَاللَّفْظُ لِدُحَيْمٍ
