Dawood Bhai, I have had to go gone back to your original post having asked about qibla and salat and thought I had shot myself in the foot by asking where the two words were linked. Could I be wrong about my understanding? Here is what you wrote:
[10:87]: And We inspired to Moses and his brother, "Settle your people in Egypt in houses and make your houses Qiblah and establish Salat and give good tidings to the believers."
1. Through 10:87, God is asking Moses and his brother to do this: (i) settle your followers in their houses (make them calm, collected, composed, and restful; no confrontation with Firaun and his people, etc.), (ii) ask them to make their houses Qibla and establish salat therein, and (iii) reassure them glad tidings from God if they remain believers.
2. Before Moses asks them to do Salat, Qibla is mentioned. People at the time of Moses knew (i) what is “Qibla” and that (ii) there is a relationship between the Qibla and Salat. Therefore, Qibla (the direction) and Salat are essential for each other.
3. It could be that their houses were to become places of salat without really bothering about a particular direction to avoid any confusion and arguments between them.
4. It could also be that no particular Qibla was yet established for this nation as no directions were yet given to Moses about the final form of the Deen and its central symbol towards which they may face eventually. Please note at this stage the only demand on Firaun is “Let Children of Israel go with me.”
I agree with points one and two, though not with your word in brackets “Qibla (the direction)”, there is a relationship between Qibla and Salat and I ask you to stand by these, your points 1 and 2, as I progress.
Point 3 you suggest that salat is to be established in their homes without a particular direction. If the Quran had stated that they should establish salat in their homes without mentioning the word qibla, then this could be understood this way. BUT, this is Allah we are talking about and as such, He does not place a word in a verse without purpose, to have it ignored or abrogated to nothingness by a wrong interpretation of its meaning. If Qibla is a direction to pray in then no particular direction is not a direction, not a qibla!
Point 4 is also false, if no directions were given then why mention Qibla, as per my point 3 observation? You wrongly claim that Moses only had his snake and only told pharaoh to let the people go, but this is contradicted by the Quran that says Moses had inspiration and presented the ‘truth’ so had revelation from Allah to present to them. Another false assumption based on a pre-existing false understanding of the word qibla, since if they had no 'revelation' up to this point then we can do away with the Qibla at this point even though it is mentioned! Qibla is mentioned in the verse and you have presented points 3 and 4 to change the meaning of the verse to your understanding.
Having established a relationship between qibla and salat in point 1 and 2, you break the relationship with your points 3 and 4!
We are now left with two scenarios:
1. the followers of Moses made each of their homes a direction to pray in, praying either towards their own homes whilst inside and out, or towards the homes of others, in haphazard, nonsensical acts of physical prostration,
2. The understanding of the Quran has to be other than a direction to turn to in prayer for the meaning of qibla.
