1. Ikhlas (sincerity) is the highest station of love and servitude to God, defined as purging actions of all impurities like self-love and desire for praise.
2. True sincerity means keeping actions free from any role of other-than-God and not desiring worldly rewards.
3. While correctly performing actions is important, true sincerity lies in persevering without polluting the intention through riya' (showing off) or self-love. Intention is the key to the perfection or defectiveness of worship.
