Ya Shayk, by the blessings of Allah عز وجل I make my whole night useful without sleeping. I am not able to sleep during night even after I have tried. I only sleep after sunrise. My question is, is this against the Sunnah ? I only feel sleepy around the time of Fajr but I dont go to sleep during that time due to prayer. But is this wrong? Is it compulsory for me to sleep during night ?
