Surah 41. Fussilat, Ayah 35

The moral standard referred to in the last verse can only be reached by the exercise of the highest patience and self-restraint. All sorts of human weaknesses and counsels of pseudo-wisdom and "self-respect" will keep breaking in, but resist them as suggestions of Evil (see next verse). If you reach anywhere near that high standard, you will be indeed most fortunate in a spiritual sense, for Allah's Revelation will have made you great and free.
