To do good with $ many Muslims wrongly perceived that the first thing to do is to donate to or build a mosque yet the Quran tells us at 2:177 ...
" Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in Allah, the Last Day, the angels, the Book, and the prophets and GIVES WEALTH, IN SPITE OF LOVE FOR IT, TO RELATIVES, ORPHANS, THE NEEDY, THE TRAVELLER, THOSE WHO ASK [for help], AND FREEING SLAVES; [and who] establishes prayer and gives zakah; [those who] fulfill their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous."
NOTE: Notice that the verse did not say only give help to Muslims.
Somehow the message of the Quran have not reached the Muslim even here Malaysia which Islam have taken roots for hundreds of years.
