I have seen especially women reciting verses from Holy Quran, part or complete surah, darood ( different kinds - Tanjeena , Taj , Ibraheemi etc etc ) , Ayat Kareema , or reciting Allah's name etc etc. They recite these in specific numbers. And they recite in group or singly to complete a given number of quantity. They do it to pray and wish for specific objective which may be either: health recovery of someone who is sick, suffering from a dangerous life threatening disease, getting a job, selling a business or for any other purposes.
My question is: Is it right per Islamic teaching? Doing this make ones prayer answered much faster? What is the significance of doing all this - gathering some women or children or man and reading as mentioned above for the purpose of achieving some objective etc ?
