'Umar said: 'Three times.' Then he (Abu Musa) left. 'Umar said to the gate-keeper: 'What did he do?' He replied: 'He left." He said: 'Bring him to me.' So when he came, 'Umar said to him: 'What is this that you have done?' He said: 'The Sunnah.' He said: 'The Sunnah? By Allah! You had better bring me proof or a witness to clarify this, or I will do this or that to you.'" He said "So he came to us while we were sitting with Ansar. He said: 'O People of the Ansar! Are you not the most knowledgeable people about the Ahadith of the Messenger of Allah (ﷺ)? Did the Messenger of Allah (ﷺ) not say: "Seeking permission is to be done three time. Either you are permitted, or other wise leave?" The people began joking. Abu Sa'eed said: "Then I raised my head toward him and said: "Whatever punishment you are afflicted with because of this, then I shall be your partner in it." So he went to 'Umar to inform him him about it, and 'Umar said: "I did not know about about this."

If it were that when he gazed into it, he was facing a man who lanced his eyes, there would be nothing wrong with him doing so.

We milked them, and each person drank his share, and we put aside a share for the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) came during the night and gave the Salam such that it would not wake the sleeping person, and the one who was awake could hear it. Then he went to the Masjid to per form Salat. Then he went for his drink and drank it."

When I saw that, I said: "'Alaikas-Salam (upon you be peace) O Messenger of Allah! 'Alaikas-Salam (upon you be peace) O Messenger of Allah! 'Alaikas-Salam (upon you be peace) O Messenger of Allah!'

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. See Tuhfat Al-Ahwadhi.

"A Jew said to his companion: 'Accompany us to this Prophet.' So his companion said: 'Do not say: "Prophet". For if he hears you (say that) then he will be very happy.'

So he said to them: 'Do not associate anything with Allah, nor steal, nor commit unlawful intercourse, nor take a life which Allah has made prohibited prohibited, except for what is required (in the law), nor hasten to damage the reputation of one of power so that he will be killed, nor practice magic, nor consume Riba, nor falsely accuse the chaste woman, nor turn to flee on the day of the march, and for you Jews particularly, to not violate the Sabbath.'" He said: "So they kissed his hands and his feet, and they said: 'We bear witness that you are a Prophet.' So he (ﷺ) said: 'Then what prevents you from following me?'
