Islam – The Religion of Peace

Prophet (peace and blessings of Allaah be upon him) said: "There are no days greater in the sight of Allaah and in which righteous deeds are more beloved to Him than these ten days, so during this time recite a great deal of Tahleel ("La ilaaha ill-Allaah"), Takbeer and Tahmeed." [Reported by Ahmad, 7/224; Ahmad Shaakir stated that it is saheeh].
