SHAHIH BUKHARI | Jilid 2 | Bab 20

And 'Ammar said, "Whoever acquires the following three qualities will acquire faith:

1. To treat others as one likes to be treated by others.

2. To greet everybody (known and unknown).

3. To spend (give charitable gifts) in Allah's Cause, in spite of poverty."

وَقَالَ عَمَّارٌ: ثَلاَثٌ مَنْ جَمَعَهُنَّ فَقَدْ جَمَعَ الإِيمَانَ الإِنْصَافُ مِنْ نَفْسِكَ، وَبَذْلُ السَّلاَمِ لِلْعَالَمِ، وَالإِنْفَاقُ مِنَ الإِقْتَارِ.
