You have completely missed the point. As Qibla is mentioned in the verse then a direction must be stated for them to pray towards. As ‘your homes’ are the Qiblas, then this negates a physical direction. Why did the Quran not say make the home of Moses a Qibla to avoid all the confusion? The reason is the Quran uses words in different scenarios and this should help us narrow down the meaning from the dictionary to the Quranic one. Homes as Qiblas must mean the followers were to make their homes a place of Deen which is the ideology, the direction of their faith, not a physical direction.
The relationship between salat, following the commands of Allah, is cemented to Qibla as this is the dirction we should be going in.
You are going to say that all the ‘ayats’, ‘signs’, were the snake and pestilence Allah burdened the Egyptians with, but here goes anyway.
Moses was a Messenger to pharaoh, so he had A MESSAGE:
43:45 Ask the Messengers We sent before you (through their messages). Did We ever appoint gods to be worshiped other than the Most Gracious?
43:46 Thus We sent Moses with OUR MESSAGES to Pharaoh and his chiefs, and he said, "I am a MESSENGER of the Lord of the Worlds."
43:47 But when he presented them OUR MESSAGES, they laughed at them.
43:48 We showed them sign after sign, each greater than the previous like of it, and We took them to task with suffering so that they may turn (to make amends). [7:133]
Ayat are signs, verses
40:23 Then We sent Moses with OUR MESSAGES and a clear authority.
40:24 To Pharaoh, Haman and Qaroon, but they said, “A spellbinding liar he is.”
[28:6, 29:39. Saahir = Magician = Trickster = An eloquent, spellbinding speaker = A deceitful liar = One who stuns the intellect. Pharaoh, Haman and Qaroon (Korah) are the archetypes of tyranny, priesthood and wealth respectively. It is important to note from this verse that Moses was sent to all three elements of this 'unholy trinity'. From this infers the mutual dependence of the forces of tyranny, priesthood and hoarding. These three elements have always worked in concert against the forces of justice and equity. Haman was the chief priest as well as chief of Pharaoh’s armies. The wealthy Qaroon belonged to the Israelites, the people of Moses. But he was Pharaoh’s slave-driver. He represents Capitalism, pursuit of wealth with its associated inequities]
40:25 When he brought THEM THE TRUTH FROM OUR PRESENCE, they said, "Kill the sons of those who have come to believe with him and spare their women." But the scheme of the rejecters came to naught. [2:49, 7:127]
40:26 Pharaoh said, "Leave it up to me to kill Moses and let him call upon his Lord. I AM AFRAID HE WILL CHANGE YOUR RELIGION and life-style and cause uprising in the land."
40:27 Moses replied, "I have found refuge with my Lord and the Lord of you all from every arrogant one who does not believe in the Day of Account."
40:28 A believing man among Pharaoh's people who had thus far concealed his faith, exclaimed, "Would you kill a man BECAUSE HE SAYS, ‘My Lord is God’, and brought you all EVIDENCE OF THE TRUTH from your Lord? If he is a liar, then his lie will fall back upon him. (He will soon be exposed.) BUT IF HE IS TRUTHFUL, then some of the punishment he warns you against, will certainly befall you. Surely, God does not guide any who transgresses and lies. [Musrif = A waster = Who transgresses beyond limits = Prodigal = One who wastes resources or own ‘self’]
You quoted 10:84 but begore that we have the Quran telling us what Moses was sent with Egypt with, with Our messages,
10:75 Then, after them, We sent Moses and Aaron to Pharaoh and his chiefs, WITH OUR MESSAGES. But they were a people arrogant and they were used to thriving on the fruit of others’ toil.
10:76 WHEN THE TRUTH FROM US came to them, they said, "This is clearly nothing but magic.”
10:77 Moses said, “IS THIS WHAT YOU SAY ABOUT THE TRUTH when it has come to you! Is this magic? Those who deceive people with lies and claims of magic, never prosper.”
10:78 They said, "Have you come to turn us away from what we found our fathers doing, so that you two become prominent in the country? We will not believe in you two."
There would be no reason to turn away from what their ancestors had given them if it were just plagues done by Allah, and not true knowledge to reform them.
Brother Dawood, we should face the Kaaba because it was intended to be the centre, our UN building, but instead we are told to pray towards it. Allah is everywhere, not just east or west, closer than our life giving vein, the brain feeder, so wherever you face you may pray to ALLAH, EVEN LOOKING UP TO THE HEAVENS. But for what purpose? Does Allah need our prayers?
Does reading back His Book and physical prostration make you a better person? Or will you improve by doing what He says and then being thankful to Him for helping you?
