1- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ اللهِ عَنْ أَبِيهِ عَمَّنْ ذَكَرَهُ عَنْ أَبِي عَبْدِ اللهِ قَالَ قَالَ رَسُولُ اللهِ ﷺ إِنَّ أَخْوَفَ مَا أَخَافُ عَلَى أُمَّتِي مِنْ بَعْدِي هَذِهِ الْمَكَاسِبُ الْحَرَامُ وَالشَّهْوَةُ الْخَفِيَّةِ وَالرِّبَا.
1. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from his father from those whom he has mentioned who has said the following: “Abu ‘Abd Allah , has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘What I fear most for my followers after me are these unlawful earnings, concealed desire and unlawful interest.’”
