“O Prophet ﷺ of Allah, I am not eloquent or a good speaker.” He said: “I have no choice but to go myself or send you with it.” Ali ؓ said: “If that is the case, I have no choice but to go.” He said: ʿGo, and Allah will make your tongue steadfast and guide your heart.ʿ Then he placed his hand over his mouth.
أَنَّ النَّبِيَّ ﷺ حِينَ بَعَثَهُ بِبَرَاءَةٌ فَقَالَ يَا نَبِيَّ اللهِ إِنِّيلَسْتُ بِاللَّسِنِ وَلا بِالْخَطِيبِ قَالَ مَا بُدٌّ أَنْ أَذْهَبَ بِهَا أَنَا أَوْ تَذْهَبَ بِهَا أَنْتَ قَالَ فَإِنْ كَانَ وَلا بُدَّ فَسَأَذْهَبُ أَنَا قَالَ فَانْطَلِقْ فَإِنَّ اللهَ يُثَبِّتُ لِسَانَكَ وَيَهْدِي قَلْبَكَ قَالَ ثُمَّ وَضَعَ يَدَهُ عَلَى فَمِهِ
