Quran Al-Baqarah 2:110
وَأَقِيمُواْ ٱلصَّلَوٰةَ وَءَاتُواْ ٱلزَّكَوٰةَۚ وَمَا تُقَدِّمُواْ لِأَنفُسِكُم مِّنۡ خَيۡرٖ تَجِدُوهُ عِندَ ٱللَّهِۗ إِنَّ ٱللَّهَ بِمَا تَعۡمَلُونَ بَصِيرٞ ١١٠
Translation
And establish prayer and give zakāh, and whatever good you put forward for yourselves - you will find it with Allāh. Indeed Allāh, of what you do, is Seeing.
