their God is One God, and their word and belief are one word and one belief. There is no distinction between them in word or deed at all, as Allah the Exalted said: {We make no distinction between any of His messengers} (Al-Baqarah 285).

And the Exalted said: {He has ordained for you of religion what He enjoined upon Noah and that which We have revealed to you, and what We enjoined upon Abraham and Moses and Jesus—to establish the religion and not be divided therein} (Al-Shura 13). And He said in Surah al-Baqarah: {Say, "We have believed in Allah and what was revealed to us and what was revealed to Abraham and Ishmael and Isaac and Jacob and the Descendants and what was given to Moses and Jesus and what was given to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [submitting] to Him"} (Al-Baqarah 136).

And likewise, the discourse regarding this manifest Prayer, which is not permissible except by facing the Kaaba, according to the saying of the Exalted: {So turn your face toward Al-Masjid al-Haram, and wherever you [believers] are, turn your faces toward it [in prayer]} (Al-Baqarah 144).
