“Once I asked Abu ‘Abdillah (a.s.) about the words of Allah, the Most Majestic, the Most Holy, ‘The month of Ramadan is the month in which the Quran was revealed, . . .’ (2:185) but there were twenty years between its first and last (words).’ Abu ‘Abd Allah (a.s.) said, ‘The Holy Quran was revealed in one piece in the month of Ramadan to Bayt al-Ma ’mur, then it was revealed in twenty years.’ The Imam said, ‘The Holy Prophet has said, “The books of Ibrahim were revealed in the first night of Ramadan, Torah was revealed on the sixth day of Ramadan, lnjil was revealed after thirteen nights of the month of Ramadan had passed, al-Zabur was revealed after twenty six days were passed from the month of Ramadan and the Holy Quran was revealed after twenty-three days had passed from the month of Ramadan.’”
