Dua Seeking easeness in speech

رَبِّ اشۡرَحۡ لِىۡ صَدۡرِىْ My Lord, expand for me my breast [with assurance] وَيَسِّرۡ لِيْٓ اَمۡرِىْ And ease for me my task وَاحۡلُلۡ عُقۡدَةً مِّنۡ لِّسَانِیْ And untie the knot from my tongue يَفۡقَهُوۡا قَوۡلِیْ That they may understand my speech. Surah Ta'ha - 20:25-28
