Surat Ghāfir - سورة غافر

فَادْعُوا اللَّهَ مُخْلِصِينَ لَهُ الدِّينَ وَلَوْ كَرِهَ الْكَافِرُونَ

: So, call you (O Muhammad SAW and the believers) upon (or invoke) Allah making (your) worship pure for Him (Alone) (by worshipping none but Him and by doing religious deeds sincerely for Allah's sake only and not to show-off and not to set up rivals with Him in worship). However much the disbelievers (in the Oneness of Allah) may hate (it).
