وَلَا تَشْتَرُوا بِعَهْدِ اللَّهِ ثَمَنًا قَلِيلًا ۚ إِنَّمَا عِندَ اللَّهِ هُوَ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ (95)
(16:95) Do not barter away the Covenant *96 of Allah for paltry gains: *97 Indeed what is with Allah is far better for you if you knew it.
*96) That is, "The Covenant that you may make in the name of Allah as a representative of His religion. "
*97) It does not mean that they should barter away Allah's Covenant for some big gain. What it implies is that any worldly gain howsoever great, is insignificant as compared with the worth of Allah's Covenant. Therefore, it will be a losing bargain to barter that away for any worldly gain, which is after all paltry.
