1.It is related by Abdullah Ibne Amr radhiyallahu anhu that the Apostle of Allah sallallahu alayhi wasallam said: “The best of you are those who possess the best of manners.”
Bukhaari and Muslim
2.Abu Hurayrah radhiyallahu anhu related to us that the Apostle of Allah sallallahu alayhi wasallam said: “Muslims who possess better morals are the most perfect in Faith”.
Abu Dawood and Daarami
3.It is related by Abu Dardaa radhiyallahu anhu, that the Apostle of Allah sallallahu alayhi wasallam said: “On the Day of Reckoning, the most weighty item in the Scales of Deeds will be good manners”.
Abu Dawood and Tirmizi
It would not be correct to assume from the above Traditions that good morals were even superior to faith or the principal tenets like Imaan, Salaat, Sawm(fasting), Zakaat and Hajj. The Holy Companions to whom these sayings were directly addressed had already learnt from the Prophet sallallahu alayhi wasallam that among the various branches of Islaam, the most important were Imaan (faith) and the doctrine of Divine Unity, and, then, came the fundamental duties. As for the rest of the departments of religious life, some of them take procedence over others in various ways, and the place of moral virtues, undoubtedly, is very high, and in the attainment of success and salvation in After-life and the gaining of the countenance of the Lord, their significance is beyond question.
4.Aaishah radhiyallahu anha relates that she heard the Apostle of Allah sallallahu alayhi wasallam say: “A Believer with good manners and a good moral disposition gets the same reward as he who fasts (permanently) and spends his nights inprayer”.
It shows that a person who is a true Muslim, both in Belief and Action, and, also, possesses good manners, but does not engage himself much in nafl (supererogatory) fasts and prayers attains the same degree of excellence, through moral goodness, as the one who, generally, stands up in prayer throughout the night and fasts all day long.
