Hadith 4:734
Muhammad ibn Bishr narrated to us, from Ibn Abi Khalid, who said: Muhammad ibn Sa’d ibn Abi Waqqas narrated to me, from his father, who said: The Prophet, peace and blessings of Allah be upon him, struck one of his hands upon the other, then said: "The month is like this and like this," and then he withheld one finger on the third [time].
