حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ، أَخْبَرَنَا سَعِيدُ بْنُ مَنْصُورٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّا، عَنِ الْحَجَّاجِ بْنِ دِينَارٍ، عَنِ الْحَكَمِ بْنِ عُتَيْبَةَ، عَنْ حُجَيَّةَ بْنِ عَدِيٍّ، عَنْ عَلِيٍّ، أَنَّ الْعَبَّاسَ، سَأَلَ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ تَعْجِيلِ صَدَقَتِهِ قَبْلَ أَنْ تَحِلَّ فَرَخَّصَ لَهُ فِي ذَلِكَ ‏.‏
