From The Saying of The Messenger of Allah (pbuh) (24)

قال رسول الله صلي الله عليه وسلم : "ما شيء أثقل في ميزان المؤمن يوم القيامة من خلق حسن فإن الله تعالى ليبغض الفاحش البذيء" الراوي: أبو الدرداء المحدث: الترمذي - المصدر: سنن الترمذي - الصفحة أو الرقم: 2002 خلاصة حكم المحدث: حسن صحيح
Abud-Darda (May Allah be pleased with him) reported: The Prophet (PBUH) said, "Nothing will be heavier on the Day of Resurrection in the Scale of the believer than good manners. Allah hates one who utters foul or coarse language" (Al-Tirmidhi)


Commentary:
In the day of Resurrection our deeds will be put on scales to be weighed .The heaviest thing on the scale will be the good manner and the noble morals so Allah (pbth )doesn't
like the obscene who pollute his mouth with hateful words.
. عن أبي هريرة رضي الله عنه قال : " سئل رسول الله صلى الله عليه وسلم عن أكثر ما يدخل الناس الجنة ؟ فقال : تقوى الله وحسن الخلق ، وسئل عن أكثر ما يدخل الناس النار ، قال : الفم والفرج " الراوي: أبو هريرة المحدث: الترمذي - المصدر: سنن الترمذي - الصفحة أو الرقم: 2004 خلاصة حكم المحدث: صحيح غريب
Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) was asked about the deed which will be foremost to lead a man to Jannah(paradise). He replied, "Fear of Allah and the good conduct.'' Then he was asked about indulgence which will admit a man to Hell (Fire) and he answered, "The tongue and the genitals".
(At-Tirmidh)
Commentary:
This is a very comprehensive Hadith.Fearing Allah (pbth) (being pious ) and the noble morals are the way to enter paradise because Allah (pbth) loves that and reward paradise for that.Allah doesn't like bad deeds .So He rewards hellfire for that and the messenger of Allah referred to "the tongue and the genitals" because all sins come from them.

Aishah (May Allah be pleased with her) reported: I heard Messenger of Allah (PBUH) saying: "A believer will attain by his good behaviour the rank of one who prays during the night and observes fasting during the day" (Abu-Dawud)
Commentary:
In this Hadith the messenger of Allah (pbuh) tells us that by the noble morals we can achieve the supreme rank of the fast .It is known that the reward of fasting is very big.
