"We are an unlettered Ummah, we do not use astronomical counting or computation. The month is like this, and this, and this," he did three times, showing it as twenty-nine.  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّا أُمَّةٌ أُمِّيَّةٌ لاَ نَكْتُبُ وَلاَ نَحْسِبُ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا ثَلاَثًا حَتَّى ذَكَرَ تِسْعًا وَعِشْرِينَ  

he heard Ibn 'Umar narrate that the Prophet said; "We are an unlettered Ummah; we do not use computation. The month is like this, and this, and this," and he held down his thumb the last time. "And the month is like this, and this, and this," completing thirty.  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّا أُمَّةٌ أُمِّيَّةٌ لاَ نَحْسِبُ وَلاَ نَكْتُبُ وَالشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَعَقَدَ الإِبْهَامَ فِي الثَّالِثَةِ وَالشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا تَمَامَ الثَّلاَثِينَ  

The Prophet ﷺ said: The month consists of twenty-nine days, but do not fast till you sight it (the moon) and do not break your fast till you sight it. If the weather is cloudy, calculate it thirty days. When the twenty-ninth of Sha'ban came, Ibn Umar would send someone (who tried) to sight the moon for him. If it was sighted, then well and good; in case it was not sighted, and there was no cloud and dust before him (on the horizon), he would not keep fast the next day. If there appeared (on the horizon) before him cloud or dust, he would fast the following day. Ibn Umar would end his fasting alone with the people, and did not follow this calculation.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّا أُمَّةٌ أُمِّيَّةٌ لاَ نَكْتُبُ وَلاَ نَحْسُبُ الشَّهْرُ هَكَذَا وَ هَكَذَا وَهَكَذَا وَخَنَسَ سُلَيْمَانُ أُصْبَعَهُ فِي الثَّالِثَةِ يَعْنِي تِسْعًا وَعِشْرِينَ وَثَلاَثِينَ  

[Machine] From the Prophet ﷺ, he said: "Indeed, we are an unlettered nation, we do not write nor calculate. And indeed, the month is like this and this and this, then it decreases one day in every third month."  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ إِنَّا أُمَّةٌ أُمِّيَّةٌ لَا نَكْتُبُ وَلَا نَحْسُبُ وَإِنَّ الشَّهْرَ هَكَذَا وَهَكَذَا وَهَكَذَا ثُمَّ نَقَصَ وَاحِدَةً فِي الثَّالِثَةِ  

[Machine] The Messenger of Allah ﷺ said, "We are an illiterate community who does not calculate or write the month like this and this and this," and he folded his thumb on the third finger.  

قَالَ رَسُولُ اللهِ ﷺ نَحْنُ أُمَّةٌ أُمِّيُّونَ لَا نَحْسُبُ وَلَا نَكْتُبُ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَقَبَضَ إِبْهَامَهُ فِي الثَّالِثَةِ  

he heard Ibn 'Umar narrate that the Prophet said; "We are an unlettered Ummah; we do not use computation. The month is like this, and this, and this," and he held down his thumb the last time. "And the month is like this, and this, and this," completing thirty. (Using translation from Nasāʾī 2141)  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ إِنَّا أُمَّةٌ أُمِّيَّةٌ لَا نَكْتُبُ وَلَا نَحْسُبُ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَعَقَدَ الْإِبْهَامَ فِي الثَّالِثَةِ وَالشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا يَعْنِي تَمَامَ ثَلَاثِينَ  

We are an unlettered people who can neither write nor count. The month is thus, and thus. folding his thumb when he said it the third time. (Using translation from Muslim 1080n)  

عَنِ النَّبِيِّ ﷺ قَالَ «إِنَّا أُمَّةٌ أُمِّيَّةٌ لَا نَحْسُبُ وَلَا نَكْتُبُ وَالشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا» وَعَقَدَ الْإِبْهَامَ فِي الثَّالِثَةِ وَالشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا تَمَامَ الثَّلَاثِينَ  

We are an unlettered people who can neither write nor count. The month is thus, and thus. folding his thumb when he said it the third time. (Using translation from Muslim 1080n)  

عَنِ النَّبِيِّ ﷺ قَالَ «إِنَّا أُمَّةٌ أُمَيَّةٌ لَا نَحْسُبُ وَلَا نَكْتُبُ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَعَقَدَ الْإِبْهَامَ فِي الثَّالِثَةِ وَالشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا تَمَامُ الثَّلَاثِينَ»  

[Machine] "The Prophet ﷺ said: 'We are an illiterate nation, we do not write or calculate. The month is like this and like this and like this,' and he folded his finger three times, meaning thirty. This Hadith is mentioned in Sahih Muslim from the narration of Shu'bah."  

النَّبِيِّ ﷺ قَالَ إِنَّا أُمَّةٌ أُمِّيَّةٌ لَا نَكْتُبُ وَلَا نَحْسُبُ وَالشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَقَبَضَ إِصْبَعَهُ وَهَكَذَا وَهَكَذَا وَهَكَذَا يَعْنِي ثَلَاثِينَ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ شُعْبَةَ  

"إِنَّا أمَّةٌ أمِّيَّةٌ، لا نَكْتب ولا نَحْسُبُ الشهر هكذا وهكذا وهكذا؛ وعقد الإِبهام في الثالثة والشَّهرُ هكذا وهكذا وهكذا. يعنى مرةً تسعةً وعشرين، ومرةً ثلاثين".
