[Machine] I have heard Anas bin Malik narrate that the Messenger of Allah ﷺ once called a young boy and measured some grain for him, either a sa' (measurement unit) or two sa's, or a mound or two mounds. The Messenger spoke to him and reduced the tax he owed.
سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ؓ يَقُولُ دَعَا رَسُولُ اللهِ ﷺ غُلَامًا فَحَجَمَهُ وَأَمَرَ لَهُ بِصَاعٍ أَوْ صَاعَيْنِ أَوْ مُدٍّ أَوْ مُدَّيْنِ وَكَلَّمَ فِيهِ فَخَفَّفَ مِنْ ضَرِيبَتِهِ
