Quran contradictions II

Does Mohammad ask for a fee?

Yes he does:

Spend your wealth for the cause of Allah, and be not cast by your own hands to ruin; and do good. Lo! Allah loveth the beneficent.
(Quran 2:195)

And know that whatever ye take as spoils of war, lo! a fifth thereof is for Allah, and for the messenger (Mohammad) and for the kinsman (who hath need) and orphans and the needy and the wayfarer, if ye believe in Allah and that which We revealed unto Our slave on the Day of Discrimination, the day when the two armies met. And Allah is Able to do all things.
(Quran 8:41)

No he does not:

Follow those who ask of you no fee, and who are rightly guided.
(Quran 36:21)

This it is which Allah announceth unto His bondmen who believe and do good works. Say (O Muhammad, unto mankind): I ask of you no fee therefor, save lovingkindness among kinsfolk. And whoso scoreth a good deed We add unto its good for him. Lo! Allah is Forgiving, Responsive.
(Quran 43:23)
