Recitation During Salah (Whispering Or Reciting In Heart)
In my understanding, the verse quoted above was specifc for Qiyam-ul-lail Salah where Muslims were asked to recite in medium pitch, somewhere between silent recitation and loud recitation. Dr Irfan Sahab can clarify further. In my understanding, one can do silent recitation which may involve some whispering as well. Reciting in one’s heart takes away the spirit of recitation ( utterance /’ tilawat ‘) altogether, therefore, utterances of Salah should be recited with lips, however the tone may vary.
