Hadith.2493 - It is narrated from Ayyub ibn A‘yan, who said
I heard Al-Walid ibn Sabih say to Abu Abdullah (as): "Abu Hanifah saw the crescent moon of Dhu al-Hijjah at Qadisiyyah and attended Arafat with us."
Abu Abdullah (as) replied: "This act has no prayer, this act has no prayer (i.e., it is not valid or accepted)."
