Zikr of Allah
Among all the ibadaat , only zikr has no limit to it. But of course what use is zikr if we don't have fikr ? In the following verse there is a warning for those who don't do zikr. Today's age when we have limited free time it is all the more important to take some time out to read Qur'an with meaning and understanding and setting some time apart for zikr and fikr . And whoever turns himself away from the remembrance of the Beneficent Allah, We appoint for him a Shaitan, so he becomes his associate. [ Surah Az-Zukhraf: 46 ]
