Kindness
مَنْ كَانَ فِي حَاجَةِ أَخِيهِ كَانَ اللَّهُ فِي حَاجَتِهِ، وَمَنْ فَرَّجَ عَنْ مُسْلِمٍ كُرْبَةً فَرَّجَ اللَّهُ عَنْهُ كُرْبَةً مِنْ كُرُبَاتِ يَوْمِ الْقِيَامَةِ
Translation
Whoever fulfills the needs of his brother, Allah will fulfill his needs. Whoever removes a hardship of a Muslim, Allah will remove one of the hardships of the Day of Judgment from him.
