ما هو التوضيح الكافي حول نطق "الله أكبر" من حيث المد، وزيادة الواو بين الكلمتين، ومد الهمزة في بداية "الله"، مع الأدلة الداعمة؟

The alif after the lam in "Allahu Akbar" is elongated with a natural madd (two vowel counts). It is not permissible to add a waw between the words "Allah" and "Akbar." It is also not permissible to elongate the hamzat al-wasl (connecting hamza) in the word "Allah" because it transforms the statement into a question, and the prayer may be invalidated if the hamza is elongated in the opening takbir.
