It was narrated from Anas bin Malik that the Messenger of Allah (ﷺ) said:The one who has the most concerns is the believer who is concerned about both his worldly affairs and his Hereafter."' (Da'if)Abu 'Abdullah said: "This Hadith is Gharib' Isma'il, alone, has narrated it."
حَدَّثَنَا إِسْمَاعِيلُ بْنُ بَهْرَامَ، حَدَّثَنَا الْحَسَنُ بْنُ مُحَمَّدِ بْنِ عُثْمَانَ، زَوْجُ بِنْتِ الشَّعْبِيِّ حَدَّثَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، عَنْ يَزِيدَ الرَّقَاشِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " أَعْظَمُ النَّاسِ هَمًّا الْمُؤْمِنُ الَّذِي يَهُمُّ بِأَمْرِ دُنْيَاهُ وَأَمْرِ آخِرَتِهِ " . قَالَ أَبُو عَبْدِ اللَّهِ هَذَا حَدِيثٌ غَرِيبٌ تَفَرَّدَ بِهِ إِسْمَاعِيلُ .
