Imam Muhammad Bin Abdul Wahhab

One is always in need of ikhlaas. The statement of ikhlaas is taken from the statement “akhlastul ‘amal lillah (I have devoted this action [sincerely] to Allah, or I have removed from this action every defect.)” Thus, nothing remains in it for other than Allah. No worldly benefits, desires, showing off, or any of the many objectives of the worldly life. The one who fulfills these conditions and battles his desires for the sake of Allah has earned the honor of being sincere, as Allah has stated:

As for those who strive hard for Our cause, We will surely guide him to Our paths. And verily, Allah is with Al-Muhsineen (good-doers).
