11 – It is Sunnah to observe i’tikaaf (retreat for the purpose of worship) in Ramadaan, because the Prophet (peace and blessings of Allaah be upon him) always did that, as it was narrated in the hadeeth of ‘Aa’ishah (may Allaah be pleased with her) that the Prophet (peace and blessings of Allaah be upon him) used to spend the last ten days of Ramadaan in i’tikaaf until he passed away, then his wives observed i’tikaaf after him.” Narrated by al-Bukhaari, 1922; Muslim, 1172.
12 – It is mustahabb in the sense of being strongly recommended in Ramadaan to study the Qur’aan together and to read it a great deal. You may study the Qur’aan together by reciting it to someone else and by having someone else recite it to you. The evidence that this is mustahabb is the fact that Jibreel used to meet the Prophet (peace and blessings of Allaah be upon him) every night in Ramadaan and study the Qur’aan with him. Narrated by al-Bukhaari, 6; Muslim, 2308.
Reading Qur’aaan is mustahabb in general, but more so in Ramadaan.
