Fussilat 41:35

<h2>The Virtue of calling Others to Allah</h2><p>وَمَنْ أَحْسَنُ قَوْلاً مِّمَّن دَعَآ إِلَى اللَّهِ</p><p>(And who is better in speech than he who invites to Allah,) means, he calls the servants of Allah to Him.</p><p>وَعَمِلَ صَـلِحاً وَقَالَ إِنَّنِى مِنَ الْمُسْلِمِينَ</p><p>(and does righteous deeds, and says: "I am one of the Muslims.") means, he himself follows that which he says, so it benefits him as well as others. He is not one of those who enjoin good but do not do it themselves, or who forbid evil yet they do it themselves.

But none is granted it (the above quality) except those who are patient, and none is granted it except the owner of the great portion (of the happiness in the Hereafter i.e. Paradise and in this world of a high moral character).

But none will attain it except those who persevere, and none will attain it except the very fortunate.
