From Sahih Muslim (Hadith 6292):
A'isha reported that Allah's Messenger (ﷺ) during his last illness) inquired:Where I would be tomorrow, where I would be tomorrow (thinking, that the turn of 'A'isha was not very near) and when it was my turn, Allah called him to his Heavenly Home and his head was between my neck and chest
