Sincerity is akin to love. Just as love between two married people must be undivided and sincere, Allah requires our complete devotion and sincerity in every act of worship and deed.

Sincerity (Ikhlas) in all forms of worship and good deeds in Islam is a fundamental measure of one’s faith (Iman). Unlike intention (Niyat), which can be either good or bad, sincerity exclusively denotes pure and good intentions. Many may perform prayers or charitable acts with ulterior motives, seeking recognition and titles such as Haji, Sincere, or Donor. True sincerity is practical and transformative, as genuine good intentions gradually cultivate authentic sincerity. This sincerity validates all acts of worship, making them acceptable. A truly sincere person dedicates all righteous deeds to Allah, showing deep devotion not only through actions but also through unwavering faith and heartfelt commitment.

What is sincerity? It is an inner state of the heart that fosters genuine devotion to Allah. This internal condition is crucial for all forms of worship and good deeds and is a fundamental aspect of Iman (faith). Several key attributes serve as indicators of true Iman and identify a genuine Muslim, including good intentions, sincerity, piety, gratitude, patience, and both fear and hope in Allah.

Allah says in the Holy Quran: “That he may test you as to which of you is best in deed.” This verse highlights two essential ways to ensure that deeds are performed purely for the sake of Allah. First, the actual way of performing good deeds. For instance, praying quickly without proper concentration is just a form without substance. Secondly, the true way that brings one closer to Allah involves cultivating sincerity in the heart. This sincerity leads to the acceptance of deeds by Allah. Therefore, the more we perform prayers and good deeds with focused concentration, the closer we come to achieving sincerity and piety.

Sincerity is beneficial in our practical lives, manifesting in various forms such as gaining Allah’s attention, resolving daily life problems, fostering piety in all situations, and strengthening our Iman as sincerity increases.

To add sincerity to your actions, consider these three points: (1) completely avoid showing off, (2) after completing a good deed, remain in a state of balance between fear and hope, and (3) perform good deeds without seeking compensation from people, such as compliments, gifts, or parties.

Sincerity is akin to love. Just as love between two married people must be undivided and sincere, Allah requires our complete devotion and sincerity in every act of worship and deed. Embracing sincerity is not optional; it is essential in all circumstances. Before embarking on any action or worship, we must prioritise sincerity. Without it, our efforts are like a business without profit.
