[2513] 16 - (...) It was narrated that Sa'd bin 'Ubaidah said: "Ibn 'Umar [may Allāh be pleased with them] heard a man saying: 'Tonight is halfway (through the month),' and he said to him: 'How do you know that tonight is halfway (through the month)? I heard the Messenger of Allāh ﷺ say: "The month is like this, and like this," and he showed ten with his fingers twice, "and like this," and he showed all his fingers the third time, but he tucked away, or hid his thumb.'"
