Must the intention and the basmalah in wudu’ be precisely at the beginning of the action? And is the intention for wudu’ for prayer sufficient for reciting the Qur’an? And is prayer permissible with wudu’ for which only an intention was made? And is rubbing obligatory with the flowing of water, or is it sufficient after it has reached [the limb]? And does wudu’ become invalidated if the prayer time expires during it or before completing a rak’ah due to delaying prayer because of scrupulousness?

Obsessive doubt (waswas) has reached a significant level, and its cure is to ignore it. The intention for ablution (wudu) is in the heart and is sufficient if made a short time before beginning the act of worship. Saying "Bismillah" (in the name of Allah) before ablution is a Sunnah (recommended), and it is not obligatory to intend whether an action is Sunnah or obligatory; rather, the intention for ablution itself is sufficient. Rubbing the limb (dalik) is sufficient while pouring water and after it, and it is originally a recommended act, not an obligatory one. If you perform ablution for the purpose of prayer, it is permissible for you to touch the Qur'an and other things. If you intend ablution to remove ritual impurity, then prayer and other acts become permissible for you. Reciting the Qur'an does not require ritual purity.

O one afflicted with obsessive doubts, it is permissible for you to adopt the easiest opinions to remove hardship. So, intend in your heart to perform ablution to remove ritual impurity or for prayer, then immediately begin washing without hesitation. Do not exceed three washes for any limb. Your ablution does not become invalidated after you finish it, even if the prayer time expires. Hasten to pray after ablution without delay, and begin the prayer without obsessive doubts. Pronounce the takbir and recitation in a normal manner without repeating letters. Do the same with all obsessive doubts: strive against them and ignore them until Allah removes them from you.
