Hadith.2088 - Abu Abdullah (as) said: "The Battle of Badr occurred in the Month of Ramadan, so the Messenger of Allah (swt) (peace and blessings be upon him and his family) did not perform i'tikaf that year. However, in the following year, he performed i'tikaf for twenty days: ten days for that year's obligation and ten days as compensation for what he had missed."
