A seeker wrote,
In salah that are offered silently (in congregation) previously I used to recite Surah al Fatiha in my mind to maintain concentration. However, now I do not find this interesting and want to do the dhikr Allah Allah in my mind. Is this appropriate?
Sayyidi wa sanadi Mufti Mohammad Taqi Usmani (Allah protect and preserve him) replied,
Contemplating about Surah al Fatiha is more appropriate.
However, (it is okay) if the dhikr Allah Allah flows out (in your mind) without your control (ikhteyar).’
