Islaam has brought noble and high characteristics out and it has cautioned us from shameful and poor characteristics.
Our beloved Prophet صلي الله عليه و سلم said:
“Verily I have been only sent to perfect and complete, righteous characteristics.” Adab Mufrad: hadeeth #273
He صلي عليه و سلم also said:
“Indeed the dearest to me amongst you and the nearest companion to me on the day of resurrection are those among you who are best in characteristics.” At-Tirmidhi: hadeeth # 1941
And He صلي الله عليه و سلم said:
“Indeed the believer will surely attain the level of the person who fasts and stands in the night (i.e.Praying at night) due to his excellence character.” Imam Ahmad: hadeeth # 25013 / Abu Dawud: hadeeth #4165
