عَنْ جَدَّتِهِ أُمِّ بُجَيْدٍ وَكَانَتْ مِمَّنْ بَايَعَ رَسُولَ اللَّهِ ﷺ أَنَّهَا قَالَتْ لَهُ يَا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْكَ إِنَّ الْمِسْكِينَ لَيَقُومُ عَلَى بَابِي فَمَا أَجِدُ لَهُ شَيْئًا أُعْطِيهِ إِيَّاهُ فَقَالَ لَهَا رَسُولُ اللَّهِ ﷺ إِنْ لَمْ تَجِدِي لَهُ شَيْئًا تُعْطِينَهُ إِيَّاهُ إِلاَّ ظِلْفًا مُحْرَقًا فَادْفَعِيهِ إِلَيْهِ فِي يَدِهِ
