The word KHAIR (خَيْر) means good, better or best. It is the opposite of bad and evil. It also means wealth and prosperity.
The prophet (saw) gave us this beautiful advice:
„Whoever believes in Allah and the Last Day, let him speek khair/good or remain silent.“
This is important because we learn in Surah Az-Zalzalah (99:7):
„Whoever does an atom‘s weight of khair/good, will see it.“
Our Focus should be on doing as much KHAIR (GOOD) as we can so we can get reward as we learn in Surah An-Naml (27:89):
„Whoever comes with a khair/good deed, will have better than it.“
So do good and KHAIR will come to you!
