All of a person’s moral values, character, the characteristics unique to him, his moods, pleasures and abilities are all shaped in the soul. If a person so wishes, and by Allah’s leave, he can greatly increase his power of the soul.
Increasing the power of the soul has no limits. If one is determined, uses one’s will properly and exhibits patience, then one can achieve an undreamed of depth of faith and moral virtue. One can obtain a force and richness of soul one had never known or experienced before.
There has always been an emphasis on improving our character in our religion Islam. The Prophet (SAW) said: “Nothing is heavier on the believer’s Scale on the Day of Judgment than good character” (Tirmidhi). From above saying we can conclude that on The Day of Judgment a person’s good character and pure heart will matter. In another hadith ‘Abu Huraira narrated: The Messenger of Allah (PBUH), said, “Allah does not look at your figures, nor at your attire but He looks at your hearts and accomplishments.”’ (Sahih Muslim)
HOW TO PURIFY SOUL?
Begin with Repentance: Allah loves those who constantly repent” (Quran, 2:222)
Pay Attention to your inner thoughts: “And We have already created man and know what his soul whispers to him, and We are closer to him than [his] jugular vein” (Quran,50:16).
Perform Obligatory Prayers: “He has succeeded who purifies himself, who remembers the name of his Lord and prays.” (Quran, 87:14-15).”Take from their wealth a charity by which you cleanse them and purify them, and invoke blessings upon them.” (Quran, 92:103).
