وَأَقِيمُواْ الصَّلاَةَ وَآتُواْ الزَّكَاةَ وَمَا تُقَدِّمُواْ لأَنفُسِكُم مِّنْ خَيْرٍ تَجِدُوهُ عِندَ اللّهِ إِنَّ اللّهَ بِمَا تَعْمَلُونَ بَصِيرٌ

(2:110) And establish the Salat and pay the Zakat. you will find with Allah whatever good you send forward for your future; Allah is watching everything you do.
