Explanation of the 26 hadith in the Heart Therapy Series:

The Prophet salla Allahu alayhi wa sallam used to make this dua:
(My Rabb, aid me and do not aid against me, grant me victory and do not grant victory over me, plot for me and do not plot against me, guide me and facilitate guidance for me, and grant me victory over those who transgress against me. My Rabb, make me to You ever-grateful, of You ever-remembering, to You ever-fearful and ever-obedient, to You ever-humble, to You oft-regretful and returning. My Rabb, accept my repentance, wash my sin away, confirm my proof, guide my heart, straighten my tongue, and remove the blackness of my heart.)
Reported by al-Nasa’i in al-Sunan al-Kubra (10552) and al-Tirmidhi (3551) and Abu Dawud (1510). Ibn Hajar declared it to be hasan, and ibn al-Qayyim, Ahmad Shakir, and al-Albani declared it to be sahih (Sahih al-Tirmidhi 3551)
كانَ رسولُ اللَّهِ ﷺ يدعو بِهَذا الدُّعاءِ: (رَبِّ أَعِنِّي ولا تُعِنْ عَليَّ وانْصُرْني ولا تَنْصُرْ عَليَّ وامْكُرْ لي ولا تَمْكُرْ عليَّ واهْدِني ويَسِّرِ الهُدَى لِي وانصُرْني على من بَغَى عليَّ رَبِّ اجْعَلْني لَكَ شَكَّارًا لَكَ ذَكَّارًا لَكَ رَهَّابًا مِطواعًا إليكَ مُخْبِتًا لَكَ أوَّاهًا مُنيبًا ربِّ تَقَبَّل تَوْبَتِي واغْسِلْ حَوْبَتي وثَبِّتْ حُجَّتي واهْدِ قَلْبي وسَدِّدْ لِساني واسْلُلْ سَخِيمَةَ قَلْبي)
