What is the ruling on supplicating to Allah using colloquial dialect?

Whoever says that Allah does not accept a prayer with grammatical errors is sinful and has contravened the Qur’an, the Sunnah, and the practice of the early Muslims (Salaf). Allah hears and answers the prayer of the sincere, whether it is grammatically correct or not. The supplicant should not force grammatical correctness if it is not their habit, as this may diminish devotion (khushu’). Similarly, it is disliked to force rhymed prose (saj’). The essence of supplication originates from the heart, and focusing on correcting one’s tongue weakens the heart’s توجه (sincere inclination). Supplication is permissible in Arabic and other languages, and Allah knows the supplicant’s intention even if their tongue is not perfectly eloquent.
