The Prophet Muhammad (peace be upon him) taught that good character is central to Islam. He stated, "I have been sent to perfect noble character" (Ibn Ishaq, as cited in Ihya Ulum al-Din, Vol. 2, p. 357). This highlights that refining and elevating moral conduct was a primary purpose of his prophethood.
The Quran itself testifies to his exceptional character, stating, "And indeed, you are of a great moral character" (Quran 68:4, cited in Ihya Ulum al-Din, Vol. 2, p. 357; Al-Risalah, Vol. 1, p. 274; Al-Gunyah, Vol. 2, p. 320). This divine affirmation underscores the profound nature of his character.
Prophet Muhammad (peace be upon him) emphasized that good character is the most beloved deed to Allah and the closest trait to him on the Day of Judgment. He said, "The most beloved of you to me and the closest to me in position on the Day of Resurrection will be those of you who have the best character" (Tirmidhi, Vol. 4, p. 372; Ihya Ulum al-Din, Vol. 2, p. 359). Conversely, bad character is described as destructive to one's deeds, like vinegar spoiling honey (Ihya Ulum al-Din, Vol. 2, p. 359).
Good character encompasses a wide range of virtues, including kindness, patience, generosity, honesty, and compassion. The Prophet (peace be upon him) taught that believers should strive to be good to all people, regardless of their background or faith. He exemplified this by being gentle and approachable, never speaking harshly, and always forgiving. He would not refuse a request unless it was something forbidden (Ihya Ulum al-Din, Vol. 2, p. 194; Al-Muwatta', Book 47, Hadith 2).
He also stressed the importance of controlling anger, stating, "Do not get angry" (Tirmidhi, Vol. 4, p. 372). Furthermore, he taught that good character is a heavy weight on the scales of deeds on the Day of Resurrection, even surpassing the reward of voluntary fasting and prayer for some (Tirmidhi, Vol. 4, p. 371; Ihya Ulum al-Din, Vol. 2, p. 359).
In essence, Prophet Muhammad (peace be upon him) taught that good character is not merely an optional aspect of faith but its very essence, a reflection of one's inner state and a path to closeness with Allah.
