NASAI-KUBRA 9183:
from Um Salamah —
[Machine] Indeed, the Messenger of Allah ﷺ had instructed us that if one of us had any written correspondence, he should complete what remained of his writing, then set it aside and inform me. Ubaidullah ibn Saad narrated this in another context and said, "If there is anything that needs to be decided regarding it, then conceal it from me."
الكبرى للنسائي ٩١٨٣:
عن ام سلمه —
إِنَّ رَسُولَ اللهِ ﷺ قَدْ كَانَ عَهِدَ إِلَيْنَا إِذَا كَانَ لِإِحْدَانَا مُكَاتَبٌ فَقَضَى مَا بَقِيَ مِنْ كِتَابَتِهِ فَاضْرِبْنَ دُونَهُ الْحِجَابَ أَخْبَرَنِي بِهِ عُبَيْدُ اللهِ بْنُ سَعْدٍ فِي مَوْضِعٍ آخِرَ وَقَالَ «إِذَا كَانَ عِنْدَ الْمُكَاتَبِ مَا يَقْضِي عَنْهُ فَاحْتَجِبِي مِنْهُ»
