إِنَّ مِنْ النَّاسِ مَفَاتِيحَ لِلْخَيْرِ مَغَالِيقَ لِلشَّرِّ ، وَإِنَّ مِنْ النَّاسِ مَفَاتِيحَ لِلشَّرِّمَغَالِيقَ لِلْخَيْرِ ، فَطُوبَى لِمَنْ جَعَلَ اللَّهُ مَفَاتِيحَ الْخَيْرِ عَلَى يَدَيْهِ ، وَوَيْلٌ لِمَنْ جَعَلَاللَّهُ مَفَاتِيحَ الشَّرِّ عَلَى يَدَيْهِ
‘Indeed from amongst the people are those who are keys to goodness and closures to evil. And indeed from amongst the people are keys to evil and closures to goodness. So tooba for the one who Allah has made him a key to goodness and wayl to the one who Allah has made a key to evil.”(1)
Shaykh Abdur Razzaq Al Badr comments on this Hadith and extracts 8 affairs if a Muslim was serious about their actualisation he would become a Key for Good and a Closure of Evil.
Fifthly: Good Manners- to adorn yourself with good noble manners and to distance yourself from bad manners that are lowly. So the possessor of noble manners his character protects him from evil and indecency, in contrast to the possessor of an evil character, for indeed his character is evil and runs towards evil and indecency.
