Ayesha reported that during the illness from which he died, the Messenger of Allah ﷺ kept asking, "Where will I be tomorrow? Where will I be tomorrow?" He meant the day of Ayesha. So his wives gave him permission to be wherever he wished, and he stayed in Ayesha's house until he died there.Ayesha said, "He died on the day that was my turn, in my house. Allah took his soul while his head was between my throat and my chest, and his saliva mingled with mine."
أن رسول الله ﷺ كان يسأل في مرضه الذي مات فيه: أين أنا غدا؟ أين أنا غدا؟ يريد يوم عائشة، فأذن له أزواجه يكون حيث شاء، فكان في بيت عائشة حتى مات عندها. قالت عائشة: فمات في اليوم الذي كان يدور علي فيه في بيتي، فقبضه الله وإن رأسه بين نحري وسحري، وخالط ريقه ريقي.
