Arabic (Original)
حَدَّثَنَا يُونُسُ حَدَّثَنَا حَمَّادٌ يَعْنِي ابْنَ سَلَمَةَ عَنْ بِشْرِ بْنِ حَرْبٍ قَالَ سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَدْعُو بِعَرَفَةَ هَكَذَا يَعْنِي بِظَاهِرِ كَفِّهِ.
English Translation
Yunus told us, Hammad - meaning Ibn Salama - told us, from Bishr ibn Harb, who said: I heard Abu Sa'id al-Khudri say: "The Messenger of Allah, peace and blessings be upon him, used to supplicate at Arafa like this" - meaning with the outer side of his palm facing him.
