Narrated Ibn `Abbas:Once I passed the night in the house of my aunt Maimuna. Allah's Messenger (ﷺ) offered the `Isha' prayer and then came to the house and offered four rak`at and slept. Later on, he woke up and stood for the prayer and I stood on his left side. He drew me to his right and prayed five rak`at and then two. He then slept till I heard him snoring (or heard his breath sounds). Afterwards he went out for the morning prayer
