From Abu Huraira رضي الله عنه he said:
The Messenger of Allah (ﷺ) was asked about the deed which will be foremost to lead a man to Jannah (paradise). He replied, “Taqwa (Fear/piety) of Allah and the good conduct.”
[Reported by At Tirmithi, Ash Shaykh Al Albaani authenticated it.]
Imam Ibnul Qaiyum said:
“The prophet صلى الله عليه و سلم combined between the fear of Allah and good manners, because fear of Allah corrects that which is between the slave and his lord, and good manners corrects that which is between him (the slave) and the creation, thus fear of Allah obligates for him love of Allah, and good manners calls the people to loving him!!”
[Al Fawaaid page 54]
May Allah make us from those who have fear of Allah and good manners.
