Islam & Youth

‎"One
of the most important things to do during these TEN days [i.e. the
first ten days of Dhu’l-Hijjah], is to repent sincerely to Allah &
to give up all kinds of disobedience & sin. Repentance means coming
back to Allah & foregoing all the deeds, open & secret, that He
dislikes, out of regret for what has passed, giving it up immediately
& being determined never to return to it" [IslamQA]
