ٱلَّذِينَ يُقِيمُونَ ٱلصَّلَوٰةَ وَمِمَّا رَزَقْنَـٰهُمْ يُنفِقُونَ
“Verily, the believers are those who when Allah is mentioned, their hearts become fearful, and when his ayat is recited, their Iman goes up, and they put their trust in Allah, the ones who pray, and who give their money. These are the true believers. They are the ones who have their ranks with Allah, and forgiveness, and noble provision.”
