Hawzah News Agency – The merciful prophet of Islam, peace be upon him and his household says:

الإيمانُ والعملُ أخَوانِ شَريكانِ في قَرَنٍ، لا يَقْبلُ اللَّهُ أحدَهُما إلّا بصاحبِهِ.

'Faith and action are two brothers, bound together with a single rope. Allah will not accept either one without the other.'
