1. Can you imagine people going about their business but facing a particular physical direction all the time? It is impossible. The only possibility is they did face a particular Qibla during prayers (salat) at particular times. People, Jews, Christians, pagans, etc., were aware of this reality since they all knew what is their Qibla. They knew and saw Muslims facing a Qibla in prayers, then changing it, and they mocked it as well.
2. Now move to 2:144.
[2:144]: “We have certainly seen the turning of your face, [O Muhammad], toward the heaven, and We will surely turn you to a qiblah (falanuwalliyannaka Qiblatan) with which you will be pleased. So turn your face toward al-Masjid al-haram. And wherever you [believers] are, turn your faces toward it. ...”
So Muhammad was turning to the heavens and not an earthly Qibla?
Where in the Quran does it say the Messenger should face a Qibla other than the Kaaba, which he was later told to change to the Kaaba?
You have already been exposed as the Quran does not mention salat with Qibla, and again since where does it say to do sujood towards the Kaaba or in Qibla?
