Muwatta Malik Book 5, Hadith 13
Malik said, "Someone who has a nosebleed on the day of jumua
while the imam is giving the khutba and he leaves and does not come
back until the imam has finished the prayer, should pray four rakas.''
Malik said that someone who prayed a raka with the imam on
the day of jumua, then had a nosebleed and left and came back and the
imam had prayed both rakas, should complete the prayer with another
raka as long as he had not spoken.
Malik said, "If some one
has a nosebleed, or something happens to him and he has no alternative
but to leave, he does not have to ask permission of the imam if he
wants to leave on the day of jumua."
Yahya related to me from Malik that Ibn Shihab used to say, "Some one who catches a raka of the jumua prayer should pray another one with it." Ibn Shihab said, "That is the sunna."
Malik said, "I saw the people of knowledge in our city doing that. That is because the Messenger of Allah, may Allah bless him and grant him peace, said, 'Whoever catches a raka of the prayer has caught the prayer.' "
Malik said, concerning some one who was in a crowd on the day of jumua and did the ruku but was not able to go into sajda until the imam had risen or finished his prayer, "If he is able to do the sajda and has already done the ruku then he should do the sajda when the people stand up. If he is unable to do thesajda until after the imam has finished the prayer, then I prefer that he begins the prayeragain and does the four rakas of dhuhr."
Yahya related to me from Malik that he had asked Ibn Shihab about the word of Allah, the Majestic, the Mighty, "O you who accept, when the call is made for the prayer on the day of jumua, make haste to the remembrance of Allah."(Sura 62 ayat 9). Ibn Shihab said, ''Umar ibn al-Khattab used to recite, 'When the call is made for the prayer on the day of jumua, go to the remembrance of Allah.' "
Malik said, "Making haste in the Book of Allah is only deed and action. Allah the Blessed, the Exalted, says 'and when he turns away, he acts in the land' (Sura 2 ayat 205), and He, the Exalted, said, 'and as for the one who comes to you acting with fear' (Sura 80 ayat 8), and He said, 'then he turned his back, and acted' (Sura 79 ayat 22),and He said, 'Your deeds are diverse' " (Sura 92 ayat 4). Malik said, "Thus making haste which Allah mentions in His Book is not running on the feet or exertion. It only means deed and actions."
