﴿ ٱلَّذِينَ يُقِيمُونَ ٱلصَّلَوٰةَ وَيُؤْتُونَ ٱلزَّكَوٰةَ وَهُم بِٱلْءَاخِرَةِ هُمْ يُوقِنُونَ ﴾

“who are constant in prayer and dispense charity: for it is they, they who in their innermost are certain of the life to come!”

who maintain the prayer alladhīna yuqīmūna’l-salāta an explication of al-muhsinīna ‘the virtuous’ and pay the alms and who are certain of the Hereafter the repetition of hum ‘they’ here translated ‘who’ is for emphasis.
