Is the prayer of one who repeated the saying of "Amen" twice, or raised his hands twice with the Takbir other than the opening Takbir inadvertently, or completed the Tasbeeh while raising his head from prostration, permissible? Does prayer become invalid due to unintentional actions? Is it permissible to make up missed prayers for 41 days, and to make up the prayers of a single day from Fajr to Isha?

Do not indulge in waswas (whispers/obsessive thoughts) as they are a cause of hardship and corruption. Saying "Ameen" is a Sunnah performed once and should not be intentionally repeated in prayer. Raising the hands twice does not invalidate the prayer. Uttering some dhikr (remembrance) of prostration while raising the head from prostration does not invalidate the prayer if done intentionally. If done forgetfully, it is said that sujood as-sahw (prostration of forgetfulness) is recommended, and it is also said that it is not. Unintentional actions in prayer: If they are of the same kind as the prayer, they invalidate it if done intentionally, but sujood as-sahw is performed for them if done forgetfully. If they are not of the same kind, many of them invalidate the prayer, while a few are excused, with no distinction between intentional and unintentional. Making up the day in which one doubts is obligatory until one is reasonably certain that they have fulfilled their obligation. One can make up five prayers in a day, and if you can do more, then do so. If you cannot, then perform as much as you are able.
