Hadith 906B2

قَالَ مَالِك : وَإِنْ كَانَ أَحَدٌ سَاكِنًا بِمِنًى مُقِيمًا بِهَا، فَإِنَّ ذَلِكَ يُتِمُّ الصَّلَاةَ بِمِنًى، وَإِنْ كَانَ أَحَدٌ سَاكِنًا بِعَرَفَةَ مُقِيمًا بِهَا، فَإِنَّ ذَلِكَ يُتِمُّ الصَّلَاةَ بِهَا أَيْضًا
Imam Malik, may Allah have mercy on him, said: If someone is a resident of Mina, he should not shorten the prayer, rather he should perform the full four units as long as he remains in Mina. Similarly, if someone is a resident of Arafat, he should also not shorten the prayer there.
