رَبِّ اشْرَحْ لِي صَدْرِي. وَيَسِّرْ لِىٓ أَمْرِى. وَٱحْلُلْ عُقْدَةً مِّن لِّسَانِى. يَفْقَهُوا۟ قَوْلِى.
My Lord, expand for me my breast [with assurance]. And ease for me my task. And untie the knot from my tongue. That they may understand my speech.
Rabbishshrah li ṣadri. Wa yassir li amri. wahlul uqdatan min lisani. yafqahu qawli
This is a particularly helpful supplication for anyone seeking to advise others or help them see right from wrong. A person who lacks patience and forbearance when dealing with others is not someone who is fit for advising others or for helping them to learn. Likewise, to be able to articulate one’s thoughts is also a necessary quality for the same objective. -Tafseer As-Sa’di and others.
