Sahih al-Bukhari 1908

حَدَّثَنَا أَبُو الْوَلِيدِ حَدَّثَنَا شُعْبَةُ عَنْ جَبَلَةَ بْنِ سُحَيْمٍ قَالَ سَمِعْتُ ابْنَ عُمَرَ ـ رضى الله عنهما ـ يَقُولُ قَالَ النَّبِيُّ صلى الله عليه وسلم " الشَّهْرُ هَكَذَا وَهَكَذَا ". وَخَنَسَ الإِبْهَامَ فِي الثَّالِثَةِ.

Abu al-Walid related to us, (he said:) Shu'bah told us. It is narrated from Jabalah bin Suhaim. He said: I heard Hazrat Ibn Umar (ra) say that the Prophet (saw), pointing with the fingers of both hands, said: “The month is this much and this much,” and the third time he folded in his thumb.
