41:33
وَمَنْ أَحْسَنُ قَوْلًا مِّمَّن دَعَآ إِلَى ٱللَّهِ وَعَمِلَ صَـٰلِحًا وَقَالَ إِنَّنِى مِنَ ٱلْمُسْلِمِينَ
waman aḥsanu qawlan mimman daʿā ilā l-lahi waʿamila ṣāliḥan waqāla innanī mina l-mus'limīna
Who speaks better than someone who calls people to God, does what is right, and says, ‘I am one of those devoted to God’?
And who is better in speech than he who [says: "My Lord is Allâh (believes in His Oneness)," and then stands firm (acts upon His Order), and] invites (men) to Allâh’s (Islâmic Monotheism), and does righteous deeds, and says: "I am one of the Muslims."
