2135 - وَ إِنَّمَا أُمِرَ بِرَمْيِ اَلْجِمَارِ لِأَنَّ إِبْلِيسَ اَللَّعِينَ كَانَ يَتَرَاءَى لِإِبْرَاهِيمَ عَلَيْهِ اَلسَّلاَمُ فِي مَوْضِعِ اَلْجِمَارِ فَيَرْجُمُهُ إِبْرَاهِيمُ عَلَيْهِ اَلسَّلاَمُ فَجَرَتْ بِذَلِكَ اَلسُّنَّةُ » وَ رُوِيَ «أَنَّ أَوَّلَ مَنْ رَمَى اَلْجِمَارَ، آدَمُ عَلَيْهِ اَلسَّلاَمُ ثُمَّ إِبْرَاهِيمُ عَلَيْهِ اَلسَّلاَمُ ».
Hadith.2135 - The command to throw the pebbles (Ramy al-Jamarat) was given because Iblis, the accursed, would appear to Ibrahim 
at the locations of the Jamarat, and Ibrahim would pelt him with stones. Thus, it became a tradition.
It has also been narrated that the first to throw the pebbles was Adam followed by Ibrahim, peace be upon him.
