Mistake #14: Wasting the last part of Ramadan preparing for Eid
Some people waste the entire last 10 days of Ramadaan preparing for Eid, shopping and frequenting malls, etc. neglecting Ibadah and Lailatul Qadr, even though the Prophet (Sal Allaahu Alaiyhi wa Sallam) used to strive the hardest during the last ten days of Ramadan in worship (Ahmad, Muslim) and not in shopping. Buy whatever you need for Eid before Ramadan so that you can maximize the time you devote to Ramadan.
