And when they meet those who believe, they say, "We believe"; but (2:14)

Almuntakhab Fi Tafsir Alquran Alkarim

And when they are face to face with those whose hearts are impressed with the image of religious and spiritual virtues they declare that they have conformed their will to Allah’s will, and when they are apart with their satanic confederates who delight in satanic wickedness, they assure them of their confederacy and that they confederate in their design but they were only laughing at the believers with an outward contempt of what they esteemed sacred

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(2:14) When they meet those who believe, they say, "We, too, are believers", but when they privily meet their evil geniuses, *15 they say, "Indeed we are with you: we are only mocking at these people".

And when they meet those who believe, they say, "We believe"; but meaning

*15). 'Satan' in Arabic means refractory, rebellious and headstrong, and is used for both human beings and jinn. Although this word is generally used in the Qur'an for the satans amongst the jinn, it is also used occasionally for human beings possessing satanic characteristics. The context generally explains whether the word 'satan' refers to jinn or to human beings. In this particular case the word 'satans' refers to those influential leaders of the time who were in the vanguard of opposition and hostility to Islam
