Q: I have a query regarding rings for men; I know that it has to be silver but I was made aware of the following hadith today:

It was narrated from ‘Abd-Allah ibn Buraydah from his father (may Allah be pleased with them both) that a man came to the Messenger of Allah (peace and blessings of Allah be upon him) and he was wearing a ring of gold. He said: “Why do I detect the stench of idols on you?” So he threw it away. Then he came and he was wearing a ring of iron, and he said: “Why do I see you wearing the jewellery of the people of Hell?” So he threw it away. He said: O Messenger of Allah, of what should I wear (a ring)? He said: “Wear (a ring) of silver, but no more than a mithqaal (a measure of weight).” Narrated by Abu Dawood, al-Tirmidhi and al-Nasaa’i.

Does this mean that the ring cannot exceed the weight of a mithqal (approx. 4.25grams) of silver at all or is it just preferable that it be that weight because according to what I heard Nabi (SAW)'s ring weighed that much.
