question #1 Sahih Muslim 875g, Book 7, Hadith 74 : What should a person do upon arriving late to the Friday sermon while the Imam is delivering it?

Sulaik Ghatafani came on Friday when the Messenger of Allah (ﷺ) was delivering the sermon. He (Sulaik) sat down. He (the Holy Prophet) said to him: 0 Sulaik I stand and observe two rak’ahs and make them short, and then said: When any one of you comes on Friday, while the Imam delivers the sermon, he should observe two rak’ahs and should make them short.
