Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ جَبَلَةَ سَمِعْتُ ابْنَ عُمَرَ يَقُولُ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الشَّهْرُ هَكَذَا وَطَبَّقَ أَصَابِعَهُ مَرَّتَيْنِ وَكَسَرَ فِي الثَّالِثَةِ الْإِبْهَامَ يَعْنِي قَوْلَهُ تِسْعٌ وَعِشْرُونَ.
English Translation
Muhammad ibn Ja'far told us, Shu'bah told us, from Jabalah: I heard Ibn Umar say: The Messenger of Allah, peace and blessings be upon him, said: The month is like this, and he closed his fingers twice, and on the third time he folded in his thumb - meaning his statement that the month may be twenty-nine days.
