Hadith.2990 - In a narration from Ali ibn Ri'ab, Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said:
"Whoever departs from Arafat with the people but does not stay with them at Jam‘ (Muzdalifah) and deliberately or out of disregard proceeds directly to Mina, must offer a badnah (a camel as expiation)."
