besides being useful, as in the Holy Quran Ayah 92 of Surah Aal-e-‘Imran        part 4, Allah عَزَّوَجَلَّ has stated:

لَنْ  تَنَالُوا  الْبِرَّ  حَتّٰى  تُنْفِقُوْا  مِمَّا  تُحِبُّوْنَ  ﱟ  وَ  مَا  تُنْفِقُوْا  مِنْ  شَیْءٍ  فَاِنَّ  اللّٰهَ  بِهٖ  عَلِیْمٌ(۹۲)

Translation from Kanz-ul-Iman: You shall never attain virtue until you spend in Allah’s cause the things you love; and Allah is Aware of whatever you spend. (Part 4, Surah Aal-e-‘Imran, Ayah 92)

Commenting on the abovementioned Ayah, ‘Allamah Maulana Sayyid Muhammad Na’eemuddin Muradabadi رَحْمَةُ اللهِ تَعَالٰی عَلَيْه has stated: Sayyiduna Ibn ‘Umar رَضِیَ الـلّٰـهُ تَعَالٰی عَـنْهُمَا said, ‘Spending here refers to general and common spending of all Sadaqat, that is, whether they are Wajib or Nafl all are included in it. Sayyiduna (Imam) Hasan Basri رَحْمَةُ اللهِ تَعَالٰی عَلَيْه has said: The wealth which Muslims like and spend for the pleasure of Allah عَزَّوَجَلَّ is included in this blessed Ayah even if it is a date.

(Sayyiduna) ‘Umar Bin ‘Abdul ‘Azeez (رَحْمَةُ اللهِ تَعَالٰی عَلَيْه) used to give sacks of brown sugar in Sadaqah after buying them. He was asked, ‘Why do you not give its price in Sadaqah’. He replied, ‘I love brown sugar; so I want to spend the thing I like most in the path of Allah عَزَّوَجَلَّ.’

صَلُّوۡا عَلَى الۡحَبِيۡب              صَلَّى اللّٰهُ تَعَالٰى عَلٰى مُحَمَّد

Dear Islamic brothers! You must have noticed that Allah عَزَّوَجَلَّ Himself is persuading us to spend the things we like most in His path. Therefore, instead of being stingy, we should generously give Sadaqah and charity with good intentions and sincerity. Of course, whatever we have, is granted by Allah عَزَّوَجَلَّ. So giving Sadaqah for His pleasure out of the wealth that He has given us will surely increase His blessings. On the contrary, despite having the ability, if we do not give Sadaqah and charity, it may become the cause of deprivation of the Divine blessings.
