Abû Dharr al-Ghifârî and Mu`âdh b, Jabal relate that the Prophet (peace be upon him) said: “Fear Allah wherever you are. Follow up a bad deed with a good deed and it will blot it out. And deal with people in a good manner.” [ Sunan al-Tirmidhî ]
The importance of this hadith:
Ibn Rajab says: “This is powerful advice, bringing together the rights of Allah and the rights of His servants.”
The fear of Allah
The Arabic word for the “fear of Allah” is taqwâ . It comes from the root word meaning “to protect from something, to prevent”. Indeed, a person exhibits the fear of Allah by seeking to prevent Allah's punishment by carrying out what Allah has commanded of him and abstaining from what Allah has prohibited him.
Allah had called upon all people in every era to fear Him. Allah says: “And We had enjoined upon those who were given the Scripture before – as well as yourselves – to fear Allah.” [ Sûrah al-Nisâ' : 131]
It is Allah's right over His servants that they fear Him as He ought to be feared. Allah says: “O you who believe! Fear Allah as He ought to be feared and do not die except as believers.” [ Sûrah Âl `Imrân : 102]
Ibn Mas`ûd explained what it means to fear Allah as He ought to be feared by saying: “It means that He is to be obeyed not disobeyed, remembered not forgotten, and shown gratitude not ingratitude.”
The fear of Allah is the path to forgiveness, salvation, and the attainment of Allah's mercy. Allah says:
“Indeed, Allah is with those who fear Him and those who do good.” [ Sûrah al-Nahl : 128]
“And My mercy encompasses all things, and I shall decree it for those who fear Me.” [ Sûrah al-A`râf : 156]
“He is worthy of being feared and worthy of granting forgiveness.” [ Sûrah al-Muddaththir : 56]
“And whoever fears Allah – He will pardon him his sins and grant him a great reward.” [ Sûrah al-Talâq : 5]
