Muslims hold that all scripture was revealed during Ramadan, the scrolls of Abraham, Torah, Psalms, Gospel, and Quran having been handed down on the first, sixth, twelfth, thirteenth (in some sources, eighteenth) and twenty-fourth Ramadans, respectively. Muhammed is said to have received his first quranic revelation on Laylat al-Qadr, one of five odd-numbered nights that fall during the last ten days of Ramadan.
