This night is the midnight (of the month). Upon this he said to him: How do you know that it is the midnight (of the month), for I heard the Messenger of Allah ﷺ as saying: The month is thus and thus (and he pointed with his ten fingers twice) and thus (i. e. at the third time he pointed with all his fingers but withdrew or folded his thumb)?
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الشَّهْرُ هَكَذَا وَهَكَذَا وَأَشَارَ بِأَصَابِعِهِ الْعَشْرِ مَرَّتَيْنِ وَهَكَذَا فِي الثَّالِثَةِ وَأَشَارَ بِأَصَابِعِهِ كُلِّهَا وَحَبَسَ أَوْ خَنَسَ إِبْهَامَهُ
