I have seen some people especially women reciting verses from Holy Quran, darūd sharīf, Ayat Karīma, or reciting Allah's name etc. They recite these in specific numbers singly or in groups. They do it to pray and wish for specific objective which may be either health recovery of someone, getting a job, selling a business or for any other purposes.
Is it right according to the Islamic teachings? Does this process make prayers answered much faster? What is the significance of gathering some women or children or men and reading as mentioned above for the purpose of achieving some objective?
