Imam Malik, may Allah have mercy on him, said that when the residents of Makkah go for Hajj, they should shorten (the prayers) at Mina, and perform two rak'ahs until they return from Hajj.

It is narrated from Hazrat Urwah bin Zubair that the Messenger of Allah, peace and blessings be upon him, performed four rak‘ahs of prayer at Mina as two rak‘ahs (i.e., he shortened them). And Sayyiduna Abu Bakr, may Allah be pleased with him, also performed two rak‘ahs there, and Sayyiduna Umar bin Khattab, may Allah be pleased with him, also performed two rak‘ahs there, and Sayyiduna Uthman bin Affan, may Allah be pleased with him, also performed two rak‘ahs at Mina until half of his caliphate, then he started performing four.

It is narrated from Sa'id bin al-Musayyib that when Sayyiduna Umar bin Khattab (may Allah be pleased with him) came to Makkah, he performed two rak'ahs and then said to the people: O people of Makkah! Complete your prayer because we are travelers. Then in Mina as well, Sayyiduna Umar (may Allah be pleased with him) performed only two rak'ahs, but it has not reached us that he said anything there.

It is narrated from Sayyiduna Aslam Adawi (may Allah be pleased with him) that Sayyiduna Umar bin Khattab (may Allah be pleased with him) performed two rak'ahs in Makkah and then said to the people: O people of Makkah! Complete your prayer because we are travelers. Then in Mina as well, Sayyiduna Umar (may Allah be pleased with him) performed only two rak'ahs, but it has not reached us that he said anything there.

Imam Malik, may Allah have mercy on him, was asked: Should the people of Mecca perform four rak'ahs or two rak'ahs in Arafat? And if the Amir al-Hajj is also a resident of Mecca, should he perform four rak'ahs or two rak'ahs of Zuhr and Asr in Arafat? And while the people of Mecca are staying in Mina, should they shorten the prayers or not? He replied: The people of Mecca, as long as they are in Mina and Arafat, should perform two rak'ahs and continue to shorten the prayers until they return to Mecca, and if the Amir al-Hajj is a resident of Mecca, he should also shorten the prayers in Arafah and Mina.

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.
