Is zakaah due on all the gold or just on that which exceeds the nisaab?

Dear Brothers & Sisters,
As-Salaamu-Alaikum wa Rahmatullahi wa Barakatuh. (May Allah's Peace, Mercy and Blessings be upon all of you)
One of our brothers/sisters has asked this question:
I want to know if the amount of gold that I have exceeds the nisaab, should I pay zakaah on the whole amount of gold or just that which exceeds the nisaab?.

Answer:
Praise be to Allaah.

You have to pay zakaah on all the gold that you have. 

The nisaab for gold is 85 grams. If a person owns one hundred grams, for example, he must pay zakaah on the entire one hundred. 

This is indicated by the hadeeth narrated by Abu Dawood (1572) from ‘Ali (may Allaah be pleased with him) who said: The Prophet (peace and blessings of Allaah be upon him) said: “If it is two hundred dirhams, then five dirhams are due, and if it is more than that, it should be worked out on that basis.” Classed as saheeh by al-Albaani in Saheeh Abi Dawood. 

This indicates that zakaah is due on the nisaab and anything more than that. 

The amount to be paid is one-quarter of one-tenth (2.5%) which may be paid from the gold itself, or the current value may be worked out and this may be paid in the form of cash. 

And Allaah knows best.

Whatever written of Truth and benefit is only due to Allah's Assistance and Guidance, and whatever of error is of me. Allah Alone Knows Best and He is the Only Source of Strength.
Your brother and well wisher in Islam
