Beneficial knowledge that is derived from the ‎Book of Allah and the Sunnah of His ‎Messenger (Sallallahu ‘Alayhi Wa Sallam). Knowledge is the foundation, and it is essential ‎for the servant to acquire in order for him to become a key to good. He who does not possess ‎beneficial knowledge, how can he distinguish between the keys to good and the keys ‎to ‎evil?! How can he distinguish between truth and falsehood?! How can he differentiate ‎between ‎what is Sunnah and what is Bid'ah (innovation)?! ‎How can he differentiate between ‎guidance and misguidance?! How can he protect himself from falsehood while he does not ‎have any knowledge?! Just as, it has been stated in the past "How ‎can one ward off that ‎which he does not know what he is warding?!"‎ As Allah says,‎

‎“Say (O Muhammad): ‘This is my way; I invite unto ‎Allah (i.e. To the Oneness of Allah - ‎Islâmic Monotheism) ‎with sure knowledge.’” [Soorah Yusuf 12:108] ‎Al-Baseerah is beneficial knowledge. ‎Therefore, he who does not have beneficial knowledge, ‎how can he separate between truth ‎and falsehood, guidance and misguidance?! ‎‏ ‏Allah ‎says, ‎

‎“Is he who walks without seeing on his face, more rightly guided, or he who (sees and) ‎walks on a Straight Way (i.e. ‎Islâmic Monotheism).” [Soorah al-Mulk 67:22]‎

‎“Shall he then who knows that what has been revealed ‎unto you (O Muhammad) from ‎your Lord is the truth be ‎like him who is blind? But it is only the men of ‎understanding that pay heed.” [Soorah Ar-Rad 13:19]‎

‎“Say: ‘Are those who know equal to those who know ‎not?’” [Soorah az-Zumar 39:9]‎

Thus, he who wants himself to become a key to ‎good then he must be diligent and concern ‎himself relentlessly with acquiring beneficial knowledge. There has been a Prophetic ‎tradition reported by ‎Al-Bayhaqi that the Messenger (Sallallahu ‘Alayhi Wa Sallam), said:‎

‎”Whoever goes out seeking to learn some beneficial knowledge, Allah will open a door ‎of Paradise for him.”‎
