Does the manner of raising the hands for the opening Takbeer affect the validity of the prayer, or is what matters most the pronunciation of the Takbeer? And is it obligatory to say the Takbeer and Tasleem aloud in prayer, or is moving the tongue sufficient? And is it permissible to follow dispensations in cases of obsessive-compulsive disorder and be satisfied with not repeating the prayer unless there is a consensus among the jurists?

Raising the hands during the takbīrat al-iḥrām (the opening takbīr) is a sunnah (recommended practice) and not a rukn (essential pillar). Voicing the takbīr aloud is not a condition for the prayer's validity; rather, it is mustaḥabb (recommended) for a person praying alone or a congregant to say it silently. For the takbīr to be valid, it is sufficient to move the tongue with the letters. It is permissible for a muqallid (follower of a specific school of thought) to adopt the sayings of different madhāhib (schools of thought) as long as he does not do so excessively, to the point of merely seeking concessions. It is forbidden to seek concessions out of desire and caprice, by the consensus of the people of knowledge. For someone suffering from waswasah (obsessive whispering), it is permissible to adopt the easiest of the madhāhib.
