2883 - رَوَى عُمَرُ بْنُ أُذَيْنَةَ قَالَ : كَتَبْتُ إِلَى أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ أَسْأَلُهُ عَنْ رَجُلٍ حَجَّ وَ لاَ يَدْرِي وَ لاَ يَعْرِفُ هَذَا اَلْأَمْرَ ثُمَّ مَنَّ اَللَّهُ عَلَيْهِ بِمَعْرِفَتِهِ وَ اَلدَّيْنُونَةِ بِهِ أَ عَلَيْهِ حَجَّةُ اَلْإِسْلاَمِ قَالَ «قَدْ قَضَى فَرِيضَةَ اَللَّهِ عَزَّ وَ جَلَّ وَ اَلْحَجُّ أَحَبُّ إِلَيَّ».
Hadith.2883 - Umar ibn Udhaynah narrated: I wrote to Abu Abdullah (as) asking about a man who performed Hajj without knowing or recognizing this [truthful] matter. Then Allah (swt) blessed him with understanding and adherence to it. Is the Hajj of Islam still obligatory upon him? Imam (as) replied: "He has fulfilled the obligation of Allah (swt), the Exalted, but performing Hajj again is more beloved to me."
