can we read surah mulk and all the other Sunnah before sleeping like (3 surahs of qul,doing tasbi,reciting ayat ul kursi etc) soon after saatul Isha or salat up magrib?? Is it permissible or we must read it only before we sleep at night??
The sunnah is to recite it right before going to bed as part of your night time athkaar.
