حَدَّثَنَا الْقَوَارِيرِىُّ حَدَّثَنَا فُضَيْلُ بْنُ عِيَاضٍ عَنْ سُلَيْمَانَ يَعْنِي الْأَعْمَشَ عَنْ أَبِي يَحْيَى عَنْ مُجَاهِدٍ عَنِ ابْنِ عَبَّاسٍ قَالَ لَوْ أَنَّ قَطْرَةً مِنْ الزَّقُّومِ فَذَكَرَهُ
مسند امام احمد بن حنبل · Hadith 3138
It was narrated from Ibn 'Abbas (RA) that he said: A woman sailed on the sea and vowed to fast for one month, then she died before she could fast. Her sister came to the Prophet (PBUH) and told him about that and he told her to fast on her behalf.
