Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 46
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «كُلُّ مَا نَاجَيْتَ بِهِ رَبَّكَ فِي اَلصَّلاَةِ فَلَيْسَ بِكَلاَمٍ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "Whatever you use to converse with your Lord عز وجل during prayer is not considered ordinary speech”.
