The Khalifah must examine the actions of the governors and continually assess their performance strictly. He must deputise people to monitor their situations, investigate them, and periodically gather all or some of them, and listen to the complaints of the subjects regarding them.

It is confirmed that the Prophet (phuh) used to test the governors when he appointed them as he did with Mu’adh and Abu Musa, and explained to them how they should proceed as he did with Amr b. Hazm in his message famous amongst the people of knowledge as mentioned by Ibn ’Asakir in Tarikh Damascus and Al-Hafiz said in Al-Isaba.

. » ... عمرو بن حزم على نج ران واس تعمل النبي ...«.

“…and the Prophet (phuh) appointed Amr Bin Hazam over Najran…” and it is reported from him that the message he wrote to him was regarding the obligations and blood money and other issues, as narrated by Abu Dawud and Al-Nasa’i, Ibn Hibban and Al-Darimi and others.

Likewise he would make them aware of some important issues as he did with Abaan Bin Said when he appointed him over Bahrain as has been mentioned in Al-Tabaqat of Ibn Sa’d from Al-Waqidi when it was said to him.

. » اسْ تَ وْصِ بَ عَ بْ دِ قَ يْسٍ خَيْراً، وَأَكْرِمْ سَرَاتَهِمْ « . “Take good care of ’Abd Qays and honour their leaders”. In the same way, it is confirmed that he used to account the governors, investigate their circumstances and listen to what was narrated to him regarding their news. He also used to account the governors over the taxation and expenditures; it is narrated by Abu Hamid Al-Sa’idi.
