If we were to give an exhaustive account of the benefits of the recitation of “Bismillahir Rahmanir Rahim” we would need more than a single volume to do justice to it. Apart from being part of every chapter in the Noble Qur’an (except the chapter of repentance – surah at-tawba), it is also the most often repeated verse in the Holy Qur’an.
It is narrated in Tafseere Burhaan that the Holy Prophet (SAW) has said that when a person recites “Bismillahir Rahmanir Rahim” then five thousand ruby palaces are built for him in Jannah. Each palace has a thousand chambers made of pearls and in each chamber has seventy thousand thrones of emerald and each throne has seventy thousand carpets made from special fabrics and upon each carpet is seated a Hur-ul-Ein. A person asked for the condition necessary to get this great reward and the Holy Prophet (SAW) replied that the person should recite the “Bismillahir Rahmanir Rahim” with conviction and understanding.
The Holy Prophet (SAW) has also said that when a believer will have to cross the Pul-e-Siraat on the Day of Judgement, and he will say “Bismillahir Rahmanir Rahim” then the flames beneath him will start dying down until Jahannam will cry out, ‘O believer, pass through quickly, your presence is causing my fire to die out!’
When a teacher teaches a child to recite “Bismillahir Rahmanir Rahim” the child, his parents and the teacher are all guaranteed freedom from hellfire. It is narrated that Prophet Isa (alayhis salam) was once passing by a graveyard and he saw a grave upon which the Wrath and Punishment of Allah SWT was descending, so he quietly walked past. When he passed the same place after some time, he noticed that the Mercy and Blessings of Allah (subhana wa-ta-’alaa) was being showered on the same grave. He was surprised at this and asked Allah (subhana wa-ta-’alaa) about what has happened and it was revealed to him that the man inside the grave was a sinner and was thus being punished for his sins. When he died, his wife was pregnant and soon gave birth to a son. When the boy grew older, his mother took him to a teacher who taught him to recite “Bismillahir Rahmanir Rahim” and I felt that it would not be justice that this man’s son was calling My Name and I was punishing his father in the grave.
It is also mentioned that recitation of “Bismillahir Rahmanir Rahim” with a loud voice is from the signs of a true believer.
May Allah make us all be among those who truly love Him. May He give us sincerity in both words and deeds Inshallah Ameen.
