اَللّٰهُمَّ افْتحْ مَسَامِعَ قَلْبِيْ لِذِكْرِكَ، وَارْزُقْنِيْ طَاعَتَكَ، وَطَاعَةَ رَسُوْلِكَ، وَعَمَلًابِكِتَابِكَ ـ

Allaahummaf-tah masaami’a qalbii lidhikrik(a), war-zuqnii taa’atak(a), wa taa’ata Rasuulik(a), wa ‘amalam biKitaabik. (‘Ali ibn Abi Taalib. Kanz al-‘Ummal #3655)

O Allah, open my heart to the hearing of Your remembrance. Grant me obedience to You and to Your Messenger (sallallahu alayhi wa sallem) and (grant me) performance of deeds according to Your Book.

Open my heart: That is, when I perform dhikr by tongue or hear it from others, it should also reach the depths of my heart.
