I have read that in the Monday dua of Imam Sajjad (as) it reads that there was no witness when Allah created the heavens and Earth. If the Noor of the Prophet (s) and Ahlulbayt (a) had already been created, would they not have been witnesses?
Allah The Exalted Has Created the Noor of the Prophet (SAWA) and Ahlul Bayt (AS) with out any witness. They were the first creatures. Creating these most sacred servants of Allah (SWT) is the start of the creation of the heavens and earth and took place with out any witness.
‘Wassalam.
