[Machine] The Messenger of Allah ﷺ said: "We are an illiterate nation, we do not write or calculate the months like this, this, this, meaning thirty. Then he said this, this, this while bending his thumb, meaning twenty-nine. He said once thirty and once twenty-nine."
قَالَ رَسُولُ اللهِ ﷺ إِنَّا أُمَّةٌ أُمِّيَّةٌ لَا نَكْتُبُ وَلَا نَحْسُبُ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا يَعْنِي ثَلَاثِينَ ثُمَّ قَالَ وَهَكَذَا وَهَكَذَا وَهَكَذَا وَضَمَّ إِبْهَامَهُ يَعْنِي تِسْعًا وَعِشْرِينَ يَقُولُ مَرَّةً ثَلَاثِينَ وَمَرَّةً تِسْعًا وَعِشْرِينَ
