Performing ´Ars prayer regularly, prohibition of praying after it

 215. Abu Basrah Al-Ghifari narrated: The Messenger of Allah salla alayhi wa sallam led us in ´Ars prayer at Mukhammas. He said: ´´This prayer (´Ars) was offered to those who were before you, but they lost it. So whoever performs it regularly, he would get its reward twice. And there is no prayer after it (´Ars) until the Shahid rises.´´ [And Al-Shahid means the star.]
