Hadith #1

1ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ وَأَحْمَدَ بْنِ مُحَمَّدٍ جَمِيعاً عَنِ ابْنِ مَحْبُوبٍ عَنِ ابْنِ رِئَابٍ عَنْ أَبِي عُبَيْدَةَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) فِي قَوْلِ الله عَزَّ وَجَلَّ فَمَنْ تَمَتَّعَ بِالْعُمْرَةِ إِلَى الْحَجِّ فَمَا اسْتَيْسَرَ مِنَ الْهَدْيِ قَالَ شَاةٌ.

1. A number of our people have narrated from Sahl ibn Ziyad and Ahmad ibn Muhammad all from ibn Mahbub from ibn Ri’ab from abu ‘Ubaydah who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that about the words of Allah, the Most Majestic, the Most Glorious, ‘One who performs al-Hajj of Tamattu’ should offer a sacrifice which he can offer.’ (2:195) He (the Imam) said, ‘It is one sheep.’
