If you compare (other) contemporaries, the same situation (comes to light), for example, if you compare Ibn ‘Awn and Ayyub al-Sakhtiyani with ‘Awf ibn Abi Jameelah and Ash‘ath Hamrani. These two (also) are students of Hasan al-Basri and Ibn Sirin just as Ibn ‘Awn and Ayyub are their students, but between these two and those two, there is a great distance in terms of excellence and accuracy of transmission. Although ‘Awf and Ash‘ath are not considered to have deviated from truthfulness and trustworthiness by the scholars, as far as rank is concerned, the reality among the scholars is as we have stated.
We have mentioned names and given examples so that for the person who is unfamiliar with the way the scholars grade the bearers of hadith, this example may serve as a clear sign through which he may gain complete understanding, and neither lower the one of high rank from his status nor raise the one of lower rank above his status, but give each his due and place him at his proper rank.
It is narrated from Hazrat ‘A’ishah Siddiqah (may Allah be pleased with her), she said: The Messenger of Allah (peace and blessings be upon him) commanded us to place people according to their ranks. Along with this is the command of Allah as stated in the Qur’an: «وَفَوْقَكُلِّذِيعِلْمٍعَلِيمٌ» “Above every possessor of knowledge is one more knowing.” [12-يوسف:76]
