After a husband and wife have intercourse is it compulsory that they get up and have a ghusl immediately or can they sleep in the state of impurity and get up earlier to have a ghusl before fajr?
Also what is the state of the person if he sleeps and passes away and doesnt have the chance to do the ghusl, passes awya before fajr. Also and if impurity gets on the matteress, how does one make it pure again? just wash the affected area thrice? as you cant squeeze it out?
