Hadith #2

2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ وَمُحَمَّدُ بْنِ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ جَمِيعاً عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) فِي قَوْلِ الله عَزَّ وَجَلَّ الْحَجُّ أَشْهُرٌ مَعْلُوماتٌ فَمَنْ فَرَضَ فِيهِنَّ الْحَجَّ وَالْفَرْضُ التَّلْبِيَةُ وَالإِشْعَارُ وَالتَّقْلِيدُ فَأَيَّ ذَلِكَ فَعَلَ فَقَدْ فَرَضَ الْحَجَّ وَلا يُفْرَضُ الْحَجُّ إِلاَّ فِي هَذِهِ الشُّهُورِ الَّتِي قَالَ الله عَزَّ وَجَلَّ الْحَجُّ أَشْهُرٌ مَعْلُوماتٌ وَهُوَ شَوَّالٌ وَذُو الْقَعْدَةِ وَذُو الْحِجَّةِ.

2. Ali ibn Ibrahim has narrated from his father and Muhammad ibn ‘Isma‘il has narrated from al-Fadl ibn Shadhan from all from ibn abu ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following: “This is about the words of Allah, most Majestic, most Glorious, ‘The months of al-Hajj are well- known, so those who owe the obligation of al-Hajj in these months . . .’ (2:197) Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that Talbiyah, marking the offering, and leading the offering animal are obligations. Whichever is done the duty of al-Hajj is complete. Al-Hajj is not performed except in the months that Allah, most Majestic, most Glorious, has called ‘well-known months’ which are Shawwal, Dhu al-Qa’dah and Dhu al-Hajj ah.’”
