Peace Bender.
Thank you once more.
Let me explain further, Why I think "salat" is part of the rites of "Millat" or " Deen"....of Abraham
2:124
Recall that Abraham was put to the test by his Lord, through certain commands, and he fulfilled them. (God) said, "I am appointing you an imam for the people." He said, "And also my descendants?" He said, "My covenant does not include the transgressors.
وَإِذِ ابتَلىٰ إِبرٰهـۧمَ رَبُّهُ بِكَلِمٰتٍ فَأَتَمَّهُنَّ قالَ إِنّى جاعِلُكَ لِلنّاسِ إِمامًا قالَ وَمِن ذُرِّيَّتى قالَ لا يَنالُ عَهدِى الظّٰلِمينَ
2:127
As Abraham raised the foundations of the shrine, together with Ismail (they prayed): "Our Lord, accept this from us. You are the Hearer, the Omniscient.
وَإِذ يَرفَعُ إِبرٰهـۧمُ القَواعِدَ مِنَ البَيتِ وَإِسمٰعيلُ رَبَّنا تَقَبَّل مِنّا إِنَّكَ أَنتَ السَّميعُ العَليمُ
2:128
"Our Lord, make us Muslims to You, and from our descendants let there be a community of Muslims to You. Teach us the rites of our religion, and redeem us. You are the Redeemer, Most Merciful.
رَبَّنا وَاجعَلنا مُسلِمَينِ لَكَ وَمِن ذُرِّيَّتِنا أُمَّةً مُسلِمَةً لَكَ وَأَرِنا مَناسِكَنا وَتُب عَلَينا إِنَّكَ أَنتَ التَّوّابُ الرَّحيمُ
2:130
Who would forsake the Millat of Abraham, except one who fools his own soul? We have chosen him in this world, and in the Hereafter he will be with the righteous.
وَمَن يَرغَبُ عَن مِلَّةِ إِبرٰهـۧمَ إِلّا مَن سَفِهَ نَفسَهُ وَلَقَدِ اصطَفَينٰهُ فِى الدُّنيا وَإِنَّهُ فِى الـٔاخِرَةِ لَمِنَ الصّٰلِحينَ
2:132
Moreover, Abraham exhorted his children to do the same, and so did Jacob: "O my children, God has pointed out the Deen for you; do not die except as Muslimeen."
وَوَصّىٰ بِها إِبرٰهـۧمُ بَنيهِ وَيَعقوبُ يٰبَنِىَّ إِنَّ اللَّهَ اصطَفىٰ لَكُمُ الدّينَ فَلا تَموتُنَّ إِلّا وَأَنتُم مُسلِمونَ
I hope this clarifies for you my understanding of why I think the rites ,including "salat" have originated from Abraham.
GOD bless you.
Peace.
