Does the prayer of one who hesitated in cutting off the Takbirat al-Ihram while performing it become invalid?

"Whoever hesitates about interrupting their prayer, their prayer is not invalidated by that, especially for those afflicted with scrupulosity (waswasah). This applies whether the hesitation occurs at the Takbirat al-Ihram (the opening 'Allahu Akbar') or afterwards. As long as the intention is firm, it is not invalidated merely by hesitation. The cure for scrupulosity is to turn away from it and not pay attention to it. So, when you pronounce the Takbirat al-Ihram, proceed with your prayer and do not repeat it or interrupt it."
