791. hadíth
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «وَ اَلْوُقُوفُ بِعَرَفَةَ سُنَّةٌ وَ بِالْمَشْعَرِ فَرِيضَةٌ وَ مَا سِوَى ذَلِكَ مِنَ اَلْمَنَاسِكِ سُنَّةٌ.
Imam Jafar ibn Muhammad Al-Sadiq (a.s) said: "Standing at Arafah is a Sunnah, and standing at al-Mash'ar is an obligation, and everything else from the rituals is Sunnah."
