Q 1: What does a person have to do
when their heart is not attuned to what they read in the Salah (Prayer)? Do they have to repeat the recitation?
The only Wajib (obligatory) recitation without which Salah becomes invalid is the recitation of Surah Al-Fatihah. All other recitations are just Sunnah (supererogatory act of worship following the example of the Prophet). Accordingly, whoever is not sure whether they have recited Al-Fatihah and they are still in the Salah; they have to recite it a second time. However, if a person frequently finds the same doubt; this is tantamount to Waswasah (Insinuating or obsessive thoughts instigated by Satan), then no attention should be paid to this.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
