[Machine] When the Messenger of Allah ﷺ went to Khaybar, he appointed Siba' bin 'Urfuta Al-Ghifari as a deputy. We arrived and witnessed the Fajr prayer with him. In the first rak'ah, he recited {Kaf Ha Ya 'Ain Sad} [Maryam 1], and in the second rak'ah, {Woe to those who give insufficient measure} [Al-Mutaffifin 1]. I said to myself, "Woe to Abu Fulan! He has two measures, and he fulfills with one and takes away with the other." We went to Siba' bin 'Urfuta and prepared a complaint. Then we went to the Messenger of Allah ﷺ either the day before or after the conquest."  

لَمَّا خَرَجَ رَسُولُ اللَّهِ ﷺ إِلَى خَيْبَرَ اسْتَخْلَفَ سِبَاعَ بْنَ عُرْفُطَةَ الْغِفَارِيَّ فَقَدِمْنَا فَشَهِدْنَا مَعَهُ صَلَاةَ الصُّبْحِ فَقَرَأَ فِي أَوَّلِ رَكْعَةٍ {كهيعص} [مريم 1] وَفِي الثَّانِيَةِ {وَيْلٌ لِلْمُطَفِّفِينَ} [المطففين 1] فَقُلْتُ فِي نَفْسِي وَيْلٌ لِأَبِي فُلَانٍ لَهُ مَكِيلَانِ يَسْتَوْفِيَ بِوَاحِدٍ وَيَبْخَسُ بِآخَرَ فَأَتَيْنَا سِبَاعَ بْنَ عُرْفُطَةَ فَجَهَّزَنَا «فَأَتَيْنَا رَسُولَ اللَّهِ ﷺ قَبْلَ الْفَتْحِ بِيَوْمٍ أَوْ بَعْدَهُ بِيَوْمٍ؟»
