Sahih Ibn Khuzaymah

Similarly, this hadith of Sayyidah Aisha (may Allah be pleased with her) states that in the beginning, when prayer was made obligatory, it was prescribed as two rak‘ahs. Then, in the case of the resident’s prayer, it was increased (and it became four rak‘ahs, while the traveler’s prayer remained two rak‘ahs). This hadith also explicitly states that a resident person is obligated to perform the complete prayer in Mina; he cannot perform shortened (qasr) prayer as long as he is a resident and not a traveler. Imam Abu Bakr (may Allah have mercy on him) says that I have explained the meaning of the narration of Sayyiduna Anas (may Allah be pleased with him) in the Book of Prayer. In the narrations of Sayyidah Aisha (may Allah be pleased with her) and Sayyiduna Ibn Abbas (may Allah be pleased with them both), there is clear evidence that it is obligatory for the people of Makkah and those residing in Makkah Mukarramah to perform the complete prayer in Mina, because they have now become residents, not travelers, and four rak‘ahs of prayer are obligatory upon the resident. Therefore, it is not permissible for any non-traveler, a person who is not fearful due to the absence of war, the people of Makkah, or a person who has come from outside and become a resident in Makkah Mukarramah, to perform shortened prayer when they go towards Mina and their intention is to return to Makkah Mukarramah. In this way, they will not be considered travelers, so it is not permissible for them to perform shortened prayer in Mina.
