Translation of "اللَّهِ" in English

يَا رَسُولَ اللَّهِ، كَيْفَ يَأْتِيكَ الْوَحْيُ ؟

O Allah's Messenger (ﷺ)! How is the Divine Inspiration revealed to you?

أَعْرِفُ أَنَّهُ لَمْ يَكُنْ لِيَذَرَ الْكَذِبَ عَلَى النَّاسِ وَيَكْذِبَ عَلَى اللَّهِ.

So I wondered how a person who does not tell a lie about others could ever tell a lie about Allah.
