Should one abandon the re-recitation of Surat Al-Fatihah and the takbirat al-ihram when in doubt about them due to waswasah (obsessive whispering), and suffice with the prostration of forgetfulness (sujud al-sahw)? Or should one act upon the predominant assumption, even though they are pillars of the prayer? And how should the intention (niyyah) be made in prayer?

Satanic whispers (waswasah) are among the most dangerous ailments that corrupt one's religion and worldly life. Their best cure is to ignore them. Do not pay attention to these whispers, and according to the most authoritative opinion, do not perform the prostration of forgetfulness (sujud al-sahw); rather, cast away doubts. As for the intention (niyyah), it is a simple matter: face the Qiblah, bring the prayer to mind with your heart, then say the opening takbir (takbirat al-ihram) without hesitation, and strive against the whispers.
