A preacher was once giving a sermon

A preacher was once giving a sermon to a large audience in the Masjid. In the course of it he said: "O People! I tell you the truth. If only you knew the power of the sentence Bismillahirrahmanirrahim (In the name of Allah, the beneficent the merciful), you would say it before every action of yours. Whoever says these words before beginning any act will see wonders. One will even be able to walk on water."

A poor villager, who was sitting close to the pulpit, listened to this sermon attentively. Poor villager was a regular visitor to the Masjid although his journey from his home was a very difficult one because he had to cross a large river on the way. Poor villager did not have a boat and often had to wait until someone appeared who could transport him across. The route around the river was extremely long. However, when the poor villager heard this sermon, he realized that he had found the solution to his problem.

When Poor villager reached the river on his way back, he did not hesitate, but recited 'Bismillahirrahmanirrahim (In the name of Allah, the beneficent the merciful)' and stepped onto the water. By the grace of Allah Subhana Wa Taala he was able to walk on the water and soon reached the other side. This became a regular practice for the poor villager, until one day, as he was crossing the river; it occurred to him that he had not thanked the preacher who had given him the solution to his problem. Poor villager decided to invite him to his house for a meal as a way of showing his gratitude to him.

The preacher accepted the invitation and both of them began walking back to the poor villager's house. On reaching the river, the poor villager recited 'Bismillahirrahmanirrahim (In the name of Allah, the beneficent the merciful)' and stepped out onto the water, as was his normal routine. Poor villager expected the preacher to do the same. But when he looked behind, he found that the preacher was still standing on the bank looking at him in bewilderment. The man told him to recite 'Bismillahirrahmanirrahim (In the name of Allah, the beneficent the merciful)' just as he had preached.

"My dear villager, I lack the faith/trust that you have," replied the preacher.

Moral of the Story: Teaching and acting on the words taught with trust is not the same. Also we must inculcate the habit of reciting 'Bismillahirrahmanirrahim (In the name of Allah, the beneficent the merciful)' before everything that we say or do in this life. Imam Jafar Sadiq Aleh Salam has said, "Do not forsake Bismillah even if you write one line of poem."
