Hadrat Imâm-i Rabbânî says in the 25th letter of the second volume of his Maktûbât: O My Son! This time of yours is a great opportunity. And opportunity is a great blessing. Times passed in good health and without anxiety are rare windfalls. You must spend each hour with the dhikr of Allâhu ta’âlâ. Every deed, even if it is shopping, which is agreeable with Rasûlullah, is dhikr. Then, every action, every attitude must be agreeable with Rasûlullah. In this case all will be dhikr. Dhikr means to dispel unawareness. In other words, it is to remember Allâhu ta’âlâ. When a person observes the commandments and prohibitions of Allâhu ta’âlâ in everything he does, in his every action, he will have escaped from forgetting the Owner of commands and prohibitions and performed dhikr all the time.
