الدعاء بسورة (يس )

Salamulaikum Dr. Ahmed one of my friends advice me to read Surrah Alyaseen everynight before sleeping because he told me his sister had read it for a particular period of time and all she asked Allah to give her He Almight subhana hu wa taala gave her from the blessings of that Surrah. Now I\'m reading the same Surrah Alyaseen everynight before sleeping keeping in my mind the thing that I want Allah subhana hu wa taala to give me from the reading of Surrah Alyaseen. I would like to ask you Sir ! Am I doing something wrong please enlighten me with the knowledge which Allah subhana hu wa taala have granted to you. Jazak Allah khairan and peace be with you. Wasalamualaikum wa rehmatullah wa barakatuhu
