Shaykh Saalih Al-Fawzaan was asked:
“What is the ruling on playing with money and scattering it during celebrations? Sometimes, it is scattered on some people by way of bragging and boasting?”
“It is not allowed. The Prophet (ﷺ) prohibited wasting money. It is obligatory to preserve the money, not to waste it and be extravagant, nor waste it in competitions and in other than that [of things] which do not have benefit. He is responsible for this wealth.
[The Prophet (ﷺ) said]:
(( لا تَزولْ قدما عبد يوم القيامة حتى يسأل عن أربع ..)) وذكر منها (( وعن ماله من أين اكتسبه وفيما أنفقه )).
The two feet of the son of Adam will not move from near his Lord on the Day of Judgement until he is asked about four (matters):[and he (ﷺ) mentioned from them] about his wealth – how he earned it; 3) and where he spent it…”
