وَضَرَبَ ٱللَّهُ مَثَلًۭا رَّجُلَيْنِ أَحَدُهُمَآ أَبْكَمُ لَا يَقْدِرُ عَلَىٰ شَىْءٍۢ وَهُوَ كَلٌّ عَلَىٰ مَوْلَىٰهُ أَيْنَمَا يُوَجِّههُّ لَا يَأْتِ بِخَيْرٍ ۖ هَلْ يَسْتَوِى هُوَ وَمَن يَأْمُرُ بِٱلْعَدْلِ ۙ وَهُوَ عَلَىٰ صِرَٰطٍۢ مُّسْتَقِيمٍۢ
And Allah coineth a similitude: Two men, one of them dumb, having control of nothing, and he is a burden on his owner; whithersoever he directeth him to go, he bringeth no good. Is he equal with one who enjoineth justice and followeth a straight path (of conduct)?
Surah An-Nahl(16:76)
Sahih al-Bukhari
Beginning of Creation
Chapter: The characteristics of Iblis (Satan) and his soldiers
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "If one says one-hundred times in one day: "None has the right to be worshipped but Allah, the Alone Who has no partners, to Him belongs Dominion and to Him belong all the Praises, and He has power over all things (i.e. Omnipotent)", one will get the reward of manumitting ten slaves, and one-hundred good deeds will be written in his account, and one-hundred bad deeds will be wiped off or erased from his account, and on that day he will be protected from the morning till evening from Satan, and nobody will be superior to him except one who has done more than that which he has done."
Sahih al-Bukhari 3293
