حَدَّثَنَا مُحَمَّدٌ، قَالَ: أَخْبَرَنَا عَبْدُ اللهِ بْنُ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِيهِ، عَنْ جَدِّهِ قَالَ: قَالَ لِي عُمَرُ: إِذَا أَرْسَلْتُكَ إِلَى رَجُلٍ، فَلاَ تُخْبِرْهُ بِمَا أَرْسَلْتُكَ إِلَيْهِ، فَإِنَّ الشَّيْطَانَ يُعِدُّ لَهُ كِذْبَةً عِنْدَ ذَلِكَ.
It is narrated from Aslam (may Allah have mercy on him) that Sayyiduna Umar (may Allah be pleased with him) said to me: When I send you to someone to call him, do not tell him why I have called him, because in this way Satan will prepare a lie for him (regarding this matter) and he will not tell the truth.
