(a) It is narrated from Sayyiduna Umar (may Allah be pleased with him) that: "Between the east and the west is the qiblah."
(b) What is meant by this is the people of Madinah, and Allah knows best. Those whose qiblah lies, like that of the people of Madinah, between the east and the west should first seek their qiblah, and then seek the exact qiblah.
