The month is thus and thus and thus (i. e. pointing with his fingers thrice), and he held back his thumb at the third time (in order to show that it can also consist of twenty-nine days). (Using translation from Muslim 1080i)  

أحمد:٤٨١٥حَدَّثَنَا رَوْحٌ حَدَّثَنَا زَكَرِيَّا بْنُ إِسْحَاقَ حَدَّثَنَا عَمْرُو بْنُ دِينَارٍ أَنَّهُ سَمِعَ عَبْدَ اللهِ بْنَ عُمَرَ يَقُولُ

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ الشَّهْرُ هَكَذَا وَهَكَذَا وَهَكَذَا وَقَبَضَ إِبْهَامَهُ فِي الثَّالِثَةِ
