"“When the name of Allah, the Most Gracious, the Most Merciful, is mentioned, thick clouds shift and move towards the east, and the wind stops, the sea becomes turbulent and wavy, the animals listen attentively, and the devils are pelted with stars from the sky. And Allah swears by His glory and majesty that nothing is named using His name except that Allah will bless it.”"

The statement above from Jabir is reinforced by a hadith from Aisha (may Allah be pleased with her), she said: "When the moments of 'bismillahir rahmanir rahim' descend, the mountains tremble, to the point that the inhabitants of Mecca hear its roar. They said, 'Muhammad has enchanted the mountains.' Then Allah sent down thick clouds to cover the inhabitants of Mecca. Then the Prophet Muhammad (peace be upon him) said, 'Whoever recites the basmalah with firm conviction, then the mountains will glorify with him, but he does not hear the sound of their glorification at all.'" (HR. Abu Na'im and ad-Dailami)

From Walid Abdul Malih, from a man he said: "I once rode on the Prophet's donkey. When the donkey stumbled, I said, 'Curse the devil!' The Prophet said, 'Do not say (dirty) words like that because the devil will grow as big as a house and say, 'I have thrown him down with my strength.' But recite bismillah, because when you recite it (bismillah) it will shrink as small as a fly," (HR. Abu Dawud and Nasai, authenticated by al-Albani).

Umayyah bin Makhsyi said, "When the Prophet Muhammad (SAW) was sitting, there was a man who was eating and did not recite the basmalah (in the name of Allah) until there was only one bite left. Then he put that bite into his mouth and recited 'bismillahi awwalahu wa akhirahu' (in the name of Allah, at the beginning and at the end). Then the Prophet laughed and said, 'The devil was still eating with him, but when he recited bismillah, the devil immediately vomited what was in his stomach.'" (Narrated by Abu Dawud)
