“Worship Allah and join not with Him in worship, and do good to parents, kinsfolk, orphans, the poor, the neighbour who is near of kin, the neighbour who is a stranger, the companion by your side, the wayfarer (you meet), and those (slaves) whom your right hand possesses. Verily, Allah does not like such as are proud and boastful.” (An-Nisaa’ 4: 36)
Allah's Messenger (peace and blessings be upon him) told us, regarding good conduct, that: “Nothing is weightier on the scale of a believing slave (of Allah) on the Day of Resurrection than good conduct and indeed, Allah dislikes the rude and disrespectful.” (At-Tirmidhee). And, the reward for this good conduct, is like that of a person who fasts and prays in the night. Prophet Muhammad, peace be upon him, said: “A Mu’min (believer) achieves by his good conduct the reward of a person who fasts much and prays in the night.” (Aboo Dawood)
When the Messenger of Allah (peace and blessings be upon him) was asked about what most frequently makes people enter Paradise, he (peace and blessings be upon him) said, "Fear of Allah and good manners." (reported in Tirmidhi). It is reported that, he said (peace and blessings be upon him), ‘Righteousness is good conduct and sin is something that is deeply rooted in your heart of which you would not like anybody to know.” (Muslim)
May Allah guide us all.
