Hadith 1101
3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ قَالَ بَعَثَنِي عُمَرُ بْنُ يَزِيدَ إِلَى أَبِي جَعْفَرٍ الأَحْوَلِ بِدَرَاهِمَ وَقَالَ قُلْ لَهُ إِنْ أَرَادَ أَنْ يَحُجَّ بِهَا فَلْيَحُجَّ وَإِنْ أَرَادَ أَنْ يُنْفِقَهَا فَلْيُنْفِقْهَا قَالَ فَأَنْفَقَهَا وَلَمْ يَحُجَّ قَالَ حَمَّادٌ فَذَكَرَ ذَلِكَ أَصْحَابُنَا لأَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) فَقَالَ وَجَدْتُمُ الشَّيْخَ فَقِيهاً.
3. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad ibn ‘Uthman who has said the following: “‘Umar ibn Yazid sent me to abu Ja’far al-Ahwal with a certain amount of dirham and asked me to tell him to perform al-Hajj with it if he wanted, or if he wanted to benefit in other ways, he can do so. He spent it for other things and did not perform al-Hajj . Certain persons of our people mentioned it to abu ‘Abd Allah (a.s.), and he (the Imam) said, ‘You have found a faqih (knowledgeable in matters of Shari ‘ah) shaykh.’”
