And who is better in speech than one who invites to Allah and does righteousness and says, "Indeed, I am of the Muslims."
The Saheeh International Quran Translation
وَمَنْ أَحْسَنُ قَوْلًا مِّمَّن دَعَآ إِلَى ٱللَّهِ وَعَمِلَ صَٰلِحًا وَقَالَ إِنَّنِى مِنَ ٱلْمُسْلِمِينَAnd who is better in speech than one who invites to Allah and does righteousness and says, "Indeed, I am of the Muslims."
