Sura Luqmān 31:4

ٱلَّذِينَ يُقِيمُونَ ٱلصَّلَوٰةَ وَيُؤْتُونَ ٱلزَّكَوٰةَ وَهُم بِٱلْأَخِرَةِ هُمْ يُوقِنُونَ

lladhīna yuqīmūna l-ṣalāta wa-yuʾtūna l-zakāta wa-hum bil-akhirati hum yūqinūna

Those who establish regular Prayer, and give regular Charity, and have (in their hearts) the assurance of the Hereafter.
