Reply To: whens the latest i can say kriyas shema al hamita????

I have great resapect for the talmedei chachomim here so please correct me if I am wrong. I don’t have a shulchan oruch here, but if I am not mistaken, in the siman on zman k”sh (about 57-58) the mechaber says that bedieved one can say keriyas shema of arvis until netz. He adds though that you can’t use the time for both shema of arvis and shacharis at same time!
