"I went to the Messenger of Allah (ﷺ) during the Year of the Conquest, and I found him performing Ghusl, while Fatimah was screening him with a garment. She said: "So I gave Salam and he said: 'Who is this?' I said: 'I am Umm Hani.' He said: 'Welcome Umm Hani'"

"When the Messenger of Allah (ﷺ) would give the Salam he would do so three times, and when he would say a statement, he would say it three times."

"The Messenger of Allah (ﷺ) was sitting in the Masjid and the people were with him when three people came. Two of them came near the Messenger of Allah (ﷺ) and one went away. When the two stopped at the Messenger of Allah (ﷺ) the said the Salam. One of them saw an opening in the circle so he sat there. As for the other one, he sat behind them, and the other one went way in the rear. When the Messenger of Allah (ﷺ) had finished, he said: 'Shall I inform you about the three people? As for one of them, he took himself to Allah so Allah took him. The other, he was shy so Allah (had mercy) on him. As for the other one, he turned away, so Allah turned away from him.'"

So he went and knocked at the door, so the Messenger of Allah (ﷺ) stood naked (1), dragging his garment - and by Allah! I did not see him naked before nor afterwards - and he hugged him and kissed him."(1) They say that the meaning of naked here is that he was not wearing his Rida or upper wrap and it was that which was dragging, so the area between the navel and knees were covered.
