The Scope of Truthfulness and Purifying the Inner Self
Sincerity (sidq), meaning truthfulness, is a fundamental pillar of Islamic morality. Sidq is not merely aligning words with reality but also ensuring that intention, behavior, and the heart are completely devoted to God. A person who has attained the station of sincerity never lies about their past actions or present circumstances. A tongue free from falsehood in the presence of God is the greatest sign that the heart is on the right path. Sufis have established this rule: if the tongue speaks truthfully, so does the heart; if the tongue speaks falsely, so does the heart. Therefore, for a seeker of truth to attain it, they must first purify their language from all exaggeration, deception, and falsehood.
Faithfulness in Expression and Preventing Misunderstandings
One of the highest degrees (perfections) of sincerity is not only speaking the truth but also avoiding ambiguous expressions that could lead to misunderstanding. This is called “avoiding Târiz.” Târiz are words that appear correct on the surface but leave a different and deceptive impression on the listener, suggesting something contrary to the truth. A believer who speaks the truth does not engage in verbal gymnastics to mislead others; their inner self reflects their outward appearance. The words of a person with an honest heart are straightforward, clear, and illuminating.
Not Backing Away from Promises Made for God’s Sake
The greatest manifestation of truthfulness and sincerity is not backing away from an intention or property dedicated for the sake of God. Spiritual masters consider that a property set aside for charity for the sake of God has left the servant’s ownership and entered God’s protection. For example, the story of the wise person who handed over his gold to someone to distribute among the poor, but when that person mistakenly returned the gold, he refused it saying, “I declared my intention for God’s sake; I will not take it back,” is a testament to the magnificent reflection of sincerity in practical life. If bread set aside for a poor person does not reach them, it is not taken back because it was intended for God’s sake but given to another needy person. This is sincerity: unwavering faithfulness in the heart.
