The Sufficient (Vol 4) · Hadith 1785 (#Ḥadīth #6)

علي بن إبراهيم، عن أبيه، عن ابن أبي عمير، عن بعض أصحابه، عن أبي عبدالله عليه السلام قال: قال: تدري لم جعل ثلاث هنا؟ قال: قلت: لا قال: فمن أدرك شيئا منها فقد أدرك الحج.

6. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from certain persons of our people who has said the following: “Abu ‘Abd Allah , asked, ‘Do you know why there are three? I replied, ‘No, I do not know. 5 He (the Imam) said, ‘It is because if one attends one of them he has attended al-Hajj.’” (Fatwa best explains this Hadith)
