Assalamu Alaikum Law,
OK...lets first look at Salaat, all of these laws are not described in the Qur'an.
Prophet Mohammad (Peace be upon him)
said “Pray as you have seen me prayingâ€Â
The Prophet (saw) taught us things that will invalidate our prayers and situations such as praying on a train or plane mean involuntary shifting of direction will not invalidate prayer.
Concealing the body - A man’s body must be covered between the navel and the knees
and also the shoulders. Women must be clothed fully with opaque covering, revealing
no shape of figure or hair at all.
Facing the Qiblah - One must face the sacred Mosque of Makkah to pray. If the direction is unknown, it
can be guessed and the prayer will be accepted, insh’Allah (“if Allah wills it soâ€Â).
Observed times of performing Salaat - Prayers are to be observed at the prescribed times.
Neglected Prayers - Salaat that is forgotten must be done even when late (“Kadaahâ€Â), the longer one leaves
it the more the reward of the prayer diminishes.
Invalidation of Salaat (that requires repeating the entire prayer)
Talking deliberately, or to do any acts outside the movements of prayer.
Laughing, eating & drinking (residual food in the mouth).
To significantly shift direction from the Ka’bah during the prayer.
Basically, everything that we do when we pray, such as folding the arms over the chest (right hand over left) after the Takbir and keeping the arms folded when ever you are standing (“Qawamâ€Â) in Salaat...etc!
There was another example, combining two sisters given in one of my posts. If you haven't read it, I would recommend you to re-read all of my posts and find it since it's an EXCELLENT example!
Zakaat is another example, go through the Qur'an and find the verses that talk about zakaat (as well as salaat)

"Be my guest, show me please the ayat that abrogated the lashing punishment for adultery?"
Brother, read my posts..you will find the answer there

I'm off to Lakemba, Salam and looking forward to reading your reply
