وَمِنَ الْأَنْعَامِ حَمُولَةً وَفَرْشًا كُلُوا مِمَّا رَزَقَكُمُ اللَّهُ وَلَا تَتَّبِعُوا خُطُوَاتِ الشَّيْطَانِ إِنَّهُ لَكُمْ عَدُوٌّ مُبِينٌ

And the heavens shall praise thy wonders, O LORD: thy faithfulness also in the congregation of the saints.

Moreover he must have a good report of them which are without; lest he fall into reproach and the snare of the devil.
