Sahih
حَدَّثَنَا هَارُونُ بْنُ إِسْحَاقَ، حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ مَا غِرْتُ عَلَى امْرَأَةٍ قَطُّ مَا غِرْتُ عَلَى خَدِيجَةَ مِمَّا رَأَيْتُ مِنْ ذِكْرِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ لَهَا وَلَقَدْ أَمَرَهُ رَبُّهُ أَنْ يُبَشِّرَهَا بِبَيْتٍ فِي الْجَنَّةِ مِنْ قَصَبٍ . يَعْنِي مِنْ ذَهَبٍ قَالَهُ ابْنُ مَاجَهْ .
