The Secrets Of Bismillah, And the Word Hittah

Question :

I would like for you to explain the secrets of the "Bismillah" and its effects on the clear verses of Allah's Book? And in the context of the following verse, what does the word "Hittah" mean?
"And say: "Forgive us (Hittah), and We shall forgive you for your sins."

Answer:

Allah Almighty legislated for us to say "Bismillah" when we are performing anything of importance, to gain blessings by His Name, to bring good, and to ward off evil. Allah Almighty says:
"Read! In the Name of your Lord".

And:
"And remember the Name of your Lord."

Before eating, drinking, engaging in sexual intercourse, entering one's home, riding a mount or a transportation vehicle, reading the Qur'an saying "Bismillah" is legislated before performing these and other actions. Verily, Allah's Name brings good and wards off evil; gaining provision and victory are some of the effects of saying this phrase.

When it is mentioned upon something that is little, that thing increases; when it is mentioned during a time of fear, it dissipates one's fears. However, for these results to occur, one must be sincere and have faith when he says, "Bismillah," as if he is saying, "When I begin my work. In the name of Allâh do I seek His help and mercy."

The word "Hittah" in this context means, "remove from us our sins." The Jews were supposed to say it when they entered Jerusalem, but instead, they changed it and said, "Hintah."
