Who is the most honourable
Abu Hurayrah (radi Allahu anhu) reported: It was asked, “O Messenger of Allah! Who is the most honourable amongst mankind?” He (sal Allahu alaihi wa sallam) said, “The most honourable of them is one who is the most pious of them.” They said, “We are not asking about this” He said, “Then, the most honourable of men was Yusuf (Joseph), the Prophet of Allah, the son of Allah’s Prophet, who was the son of the Prophet of Allah, who was the son of the Khalil of Allah (i.e., Ibrahim (alaihi assalam))’ They said, “We are not asking you about this.” He enquired, “Are you then asking me about the classes of the Arabs? The best of them in the Pre-Islamic Period of Ignorance are the best of them in Islam, provided they comprehend the religious knowledge”
[Sahih al-Bukhari and Muslim]
We come to know from this Hadith that the families which enjoyed popularity and prestige for their eminent qualities (like generosity, chivalry, honesty, etc.) in the pre-Islamic period were also credited for these values after their acceptance of Islam. But now their respect was qualified with their religious knowledge and practice. Their capabilities, self-respect and other qualities were turned towards a different direction. These qualities which were previously used for paganism were now devoted for Islam.
And Allah Knows Best!
