What is the ruling on one who stoned the pillars with gold?

The questioner : What do you say if he stoned with gold instead of stones? The Prophet used stones.

The Shaykh : For example, he is given gold beads. Twenty-one beads. On the second day, the eleventh, he went and stoned seven at the first pillar, seven at the middle pillar, and seven at the last pillar. And what is the important point?

The questioner : So , he commanded the use of stones.

The Shaykh : Yes. As we said, whoever does a deed for which there is no evidence from the Prophet (peace and blessings be upon him) has innovated. Did you hear the answer? It says: Indeed, in the Messenger of Allah (peace and blessings be upon him) is a good example. And the Prophet (peace and blessings be upon him) stoned with stones, and he said to use stones like these, as an obligation. And the Prophet (peace and blessings be upon him) said: There is another, third concern: it falls under the category of wasting wealth.
