A:
It is permissible for a Muslim to spend their money in all aspects of good and during calamities in particular. However, it is Sadaqah (voluntary charity). Allah (Exalted be He) says:
It is not Al-Birr (piety, righteousness, and each and every act of obedience to Allah, etc.) that you turn your faces towards east and (or) west (in prayers); but Al-Birr is (the quality of) the one who believes in Allah, the Last Day,
until He says:
...And gives his wealth, in spite of love for it, to the kinsfolk, to the orphans,
It was authentically reported that the Prophet (peace be upon him) said:
The wealth of a person will not diminish by giving Sadaqah.
Allah (Glorified be He) warns us against stinginess when He (Glorified and Exalted be He) says:
And let not those who covetously withhold of that which Allah has bestowed on them of His Bounty (Wealth) think that it is good for them (and so they do not pay the obligatory Zakat).
