I came to Madinah and met Aslam, the freed slave of ʿUmar bin al-Khattab. I said. Tell me(a report)from ʿUmar. He said: I cannot, I am afraid that I will add or subtract something. If we said to ‘Umar, Tell us something from the Messenger of Allah ﷺ, he would say: I am afraid that I may add or subtract a letter. The Messenger of Allah ﷺ said: “Whoever tells a lie about me will be in Hell.ʿ
لَا أَسْتَطِيعُ أَخَافُ أَنْ أَزِيدَ أَوْ أَنْقُصَ كُنَّا إِذَا قُلْنَا لِعُمَرَ حَدِّثْنَا عَنْ رَسُولِ اللهِ ﷺ قَالَ أَخَافُ أَنْ أَزِيدَ حَرْفًا أَوْ أَنْقُصَ إِنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ كَذَبَ عَلَيَّ فَهُوَ فِي النَّارِ
