When closing the door of your house, remember to recite – Shayṭān (evil Jinns) will be unable 
to enter the house. (Ṣaḥīḥ Bukhārī, pp. 591, vol. 3, Ḥadīš 5623


This verse is translated as “In (or with) the name of Allah, who is Beneficent and Merciful”. Here, the particle “Bi” (meaning inor with) in the word “Bism” represents a call for help. So the verse means:

“With the help of the name of Allah…”

Now it is apparent that a verb or action is implied in this sentence and by studying the Quran one realizes that this verb is iqrawhich means ‘read’ or ‘recite’. This is in line with the hadith where it is written that an angel appeared to the Holy Prophet, while he was engaged in his usual worship of God at the cave of Hira. The angel said: iqra, i.e. read. The Holy Prophet replied: “I do not know how to read”. The angel repeated the same words and the Holy Prophet repeated his answer. And so it happened three times. The fourth time the angel said: Iqra bismi rabbi-ka alladhi khalaq, i.e. read in the name of your Lord who created (the Holy Quran, 95:1). Then the Holy Prophet started reciting. So it is clear that the verb implied before “In the Name of Allah” is iqra, i.e. to read or recite with the name of Allah. This verb is not explicitly stated because when a person recites the Quran, the use of the word iqra, which is a command, would not be eloquent. The worshipper at that time is fulfilling the order. Therefore at the time of recitation the implied verb is aqrau, i.e. “I read”. The subtlety in this is that when the revelation descended from God, then because the sentence reflects a command of God, so the implied verb is iqra, i.e. “Read” (imperative), and when the worshipper recites the Quran then because he is at that time fulfilling the commandment of God, the implied verb would be understood to be aqrau i.e. “I read or recite with the help of the name of God…”
Another advantage of keeping the verb implicit is that when a person recites bismillah ar-rahman ar-rahim at the beginning of any work then whatever he is going to do would be considered implied in the sentence. That is, this call for God’s help is not restricted to the recitation of the Holy Quran but is asked for at the beginning of each and every work so that God’s help is asked for in that work. Thus in the hadith “kul amr la yabd fihi bismillah ar-rahman ar-rahim fa huwa ajzam,” that is “any work started without reciting bismillah ar-rahman ar-rahim is without blessing”, and certainly if any person starts his works by asking for the help of God then his work will be blessed.
